2. The article

In a two-year FBI sting, agents posing as agents of a rich Arab sheik offered cash and favors to public officials and videotaped what happened; the tapes led to the conviction of one senator and six House members, the first House expulsion since the Civil War era, and the first written Justice Department rules for undercover work.

In brief

In 1978 the FBI built a fake company owned by an invented Arab sheik and used it to offer money to public officials, with hidden cameras running. Over the next year, at least twelve members of Congress were offered cash. Seven took it: a senator and six House members, six of them Democrats and one a Republican. At least five did not. No one has published a full list of everyone who was approached, so no exact percentage exists, and the story reached voters through leaks, trials and tapes rather than any systematic disclosure. The sting ended on February 2, 1980, because NBC reported it, not because anyone chose to stop. The Justice Department's first written rules for undercover work came a year later. Courts rejected entrapment claims on appeal, but a Senate committee found the FBI had run it without guidelines and had put innocent officials before the cameras. For voters the lesson is mixed: the tapes showed what no disclosure form could, and the process still left them with partial and uneven information.

The record

The two questions Frank asked

Question 1: What percentage of the officials approached took the money?

Short answer: no one has published a full list of everyone who was approached, so no exact percentage exists. For members of Congress, the best documented count is 12 offered, 7 took it, 5 did not: 7 of 12, about 58 percent. That is a floor on the number approached, not a total.

The arithmetic, with the source for each line:

Group Count Source
Members of Congress convicted (took the money) 7: Sen. Harrison Williams (D-NJ); Reps. Frank Thompson (D-NJ), John Jenrette (D-SC), Raymond Lederer (D-PA), Michael "Ozzie" Myers (D-PA), John Murphy (D-NY), Richard Kelly (R-FL) Senate Select Committee report, S. Rept. 97-682, p. 2 ("a United States Senator, six Members of the" House); Senate expulsion page
Members of Congress offered money who did not accept 5: Sen. Larry Pressler (R-SD), Reps. Edward Patten (D-NJ), John Murtha (D-PA), Raphael Musto (D-PA), James Mattox (D-TX) FBI Legal Counsel Division memo on "ABSCAM," about Feb. to Mar. 1982, in the FBI Vault Murtha file: "six Congressmen were contacted by intermediaries and were proffered money"; "None of the six accepted"
A sixth name on that memo Rep. Peter Rodino (D-NJ). The memo says he "was never personally contacted by FBI representatives" and that offers were made for his help to others. We do not count him as approached. Same memo
Documented total offered 12 7 + 5
Took it 7 of 12 = 58.3 percent Our math
Did not take it 5 of 12 = 41.7 percent Our math

How each of the five who did not accept responded (same FBI memo): Pressler "flatly declined" and is described as the only one who did; Patten "made no response to the offer and never directly indicated that he perceived that a bribe offer was being made"; Murtha was contacted on several occasions, said he would get back in touch, and never recontacted the offeror; Musto "was offered a bribe on one occasion and did not accept"; Mattox "did not accept the offer" but later testified that he knew he had been offered a bribe. So only one of the five clearly refused on the spot. A Boston College Law Review note says "all but three" of the officials who met agents on tape accepted, and names the three who declined as Pressler, Patten and Murtha (Notes, "The Abscam Investigation," 25 B.C. L. Rev. 351, 352 n.14, citing the Myers trial court opinion, 527 F. Supp. 1206, 1225).

Other counts you will see, and what each actually counts:

What was disclosed and what was not:

Party breakdown, and the "mostly Democrats" question

Party of the members of Congress in the documented groups, and of the Congress they sat in:

Group Democrats and Republicans Share Democratic
Convicted (7) 6 D, 1 R (Kelly) 86 percent
Documented offered, taken or not (12) 10 D, 2 R (Kelly, Pressler) 83 percent
House at start of the 96th Congress (Jan. 1979) 276 D, 156 R (plus 1 Conservative, 2 vacant) about 64 percent of 433 seated
Senate at start of the 96th Congress 58 D, 41 R (plus 1 independent) 58 percent
Both chambers combined 334 D, 197 R about 63 percent of the 531 who were D or R

The seat counts are from the Wikipedia "96th United States Congress" party-division table. The same page's summary box gives different Senate numbers (57 D, 42 R), and we did not confirm either against the House Clerk or the Senate Historical Office, so treat the exact seat counts as approximate. The party of Patten, Murtha, Musto, Mattox, Pressler and the others is from the standard biographical directories as we remember them, except for Musto, which we confirmed (Wikipedia: Democrat, PA-11, in the U.S. House Apr. 9, 1980 to Jan. 3, 1981); we did not re-fetch the others in this pass.

Our math on whether this is just chance: if 7 convicted members were drawn at random from a Congress that was about 63 percent Democratic, the chance of getting 6 or more Democrats is about 20 percent (7 x 0.63^6 x 0.37 + 0.63^7 = 0.162 + 0.039). For the 12 documented offered, the chance of 10 or more Democrats is about 12 percent. Neither is below the usual 5 percent bar, and with numbers this small and a non-random selection process it proves nothing in either direction. What the numbers do say: yes, most of those convicted were Democrats (6 of 7), which matches the usual summaries, and the sample is also close to the share of Democrats in Congress. The selection was not random. The middlemen who brought officials to the tapes were themselves Democratic officeholders or associates (Errichetti, a Democrat, and the Philadelphia lawyer Howard Criden), and recruited from networks in Camden, Philadelphia and New Jersey Democratic politics (Pace L. Rev., p. 1572, on Errichetti and Criden's roles; Myers, 692 F.2d 823, on how Thompson, Murphy, Myers and Lederer were brought in). The Senate committee found the FBI did not "abandon or fail to follow any investigative lead for any improper purpose" (p. 13) and that "there is no evidence that these leaks were politically motivated" (p. 14), but it also did not decide whether the targeting was fair to everyone.

Question 2: Why was it stopped?

Short answer: the secret stage ended because it became public. The documented chain is a media leak on February 2, 1980, not a decision by Congress or the courts. Reforms followed afterward. The deeper question of whether the FBI would have continued, and whether more members would have been caught, is asserted but not documented.

Timeline

What this case shows

The question: voters face barriers to knowing and judging their representatives. Abscam is a case where the barrier was visible and then briefly lifted, and the way it was lifted raises its own questions.

  1. Video evidence showed voters what no disclosure rule would have. Campaign finance reports and financial disclosures list what officials report. They do not show a member of Congress accepting an envelope of cash and saying he can introduce a private bill. The tapes shown at trial gave voters and colleagues the unusual ability to judge officials by their own words, such as Myers: "Absolutely. Where I could be of help in this type of a matter, first of all, is private bills that can be introduced" (692 F.2d 823), and Jenrette: "I got larceny in my blood" (744 F.2d 817). Without a sting, voters have no tool for this.
  2. Even the tapes reached voters unevenly. Most of what the public knew in February 1980 came from leaks, not from any official disclosure. The Senate committee found the leaks hurt "unquestionably innocent individuals" and that no one was identified or punished for them (pp. 14, 22). Pressler, who refused and reported the approach, was among those whose names circulated in the press. A voter in that month could not tell who took money and who did not, which is the opposite of what a well-informed electorate needs.
  3. Nobody published the full denominator. We can state that 7 members took the money and at least 5 did not (about 58 percent). We cannot state how many were approached overall, because the FBI and Justice Department never released a complete list, and the committee did not name the innocent officials who were brought before the cameras. A voter cannot judge whether an official who was approached and said no did the right thing, because the "no" often is not on the public record.
  4. When voters did learn, they did not always act as accountability theory predicts. Secondary sources say Lederer was reelected in November 1980 after the sting was public, while Kelly lost his primary and Thompson and Murphy lost at the polls (EBSCO Research Starters). Myers kept campaigning after he was expelled. We have not verified these results against election returns. If true, voters with the same information reached different judgments, which cuts against both "voters need only more information" and "voters cannot be trusted."
  5. Institutions policed themselves unevenly. The House expelled Myers 376 to 30 and the Senate was about to expel Williams. In Murtha's case the House Ethics Committee declined to file charges in a mostly party-line vote in July 1981 (Wikipedia; one source describes the special counsel's resignation the same day as a protest). Those facts appear in a single secondary source, but they show that the same video can lead to different institutional outcomes for different members. The voters in each district saw only the result.
  6. The rules came after the fact. The Senate committee found there were no Justice Department guidelines when Abscam began (p. 12). The first written rules arrived in January 1981, once the sting was over. Voters, through their representatives, did not have any say in the rules under which their representatives were being tested.

The strongest objections, and our answers

  1. Objection: This is a corruption case, not a voting-barrier case. Mitigation: Agreed. The tie to the thesis is indirect. Nobody was prevented from voting. The link is the information problem: how voters learn what their representatives do and say in private. We should not say Abscam shows disfranchisement.
  2. Objection: It was entrapment; the FBI manufactured crimes. Mitigation: Every court that reached the question on appeal rejected it for the congressional defendants, and nine juries convicted each defendant who appeared before them (Senate report, p. 12). But the picture is mixed: trial judges in Jannotti and Kelly set verdicts aside, the Senate committee found serious deficiencies in how Weinberg and the middlemen were managed (pp. 17 to 19), and the committee said it was not deciding entrapment (p. 13). Present both: the law as applied, and the concerns that led to the guidelines and to the proposed objective test.
  3. Objection: Most of those convicted were Democrats, so this was a partisan hit. Mitigation: Six of seven convicted members were Democrats, and about 63 percent of Congress was Democratic at the time, so the share is higher than their seat share but not outside what chance could produce with numbers this small (about 20 percent by our math). The middlemen came from Democratic networks, which is a plausible explanation for the overlap. A Republican (Kelly) was convicted and a Republican (Pressler) refused. The Senate committee found no evidence the leaks were politically motivated (p. 14) and that the FBI did not drop leads improperly (p. 13). We cannot rule out selection effects, and the committee did not test that.
  4. Objection: The percentage who "took the money" is meaningless because many were shown the offer by a middleman and never knew it was a bribe. Mitigation: True for some. The Senate committee found at least one innocent official was brought before the cameras (p. 19). That is why our headline figure is limited to members of Congress who were offered money and why we say 12 is a floor. We also separate Patten (no response) and Rodino (never contacted) from clear refusals.
  5. Objection: Five who "did not accept" is not the same as five who refused. Mitigation: Correct, and we say so. Only Pressler flatly declined. Murtha said he would get back to the offeror and did not. Musto and Mattox "did not accept." If the question is "who turned it down on the spot," the answer is closer to 1 in 12 than 5 in 12.
  6. Objection: The tapes cannot be trusted; the central witnesses were liars. Mitigation: The Senate committee said uncorroborated testimony from the central figures (Weinberg, Errichetti and others) "has almost no probative value" and that each "appears willing to fabricate evidence to serve his own interests." But the convictions rested on videotapes and recorded money transfers, and the committee found none of the defendants was "merely playacting."
  7. Objection: Williams and others said the money was to a business, not a bribe. Mitigation: Williams was convicted of promising to use his influence to win a government contract in return for a stake in a titanium venture; the Senate Ethics Committee unanimously found his conduct "ethically repugnant," and the Second Circuit found sufficient evidence of predisposition.
  8. Objection: This was a one-off from 1980 and tells us nothing about today. Mitigation: Fair. The Civiletti guidelines were revised in 1983, 1989 and 2001 (Wikipedia), so the rules in this case no longer apply as written. We make no claim about today in this case.
