Washington ? The new chief of the FBI’s Criminal Division, which is swamped with public corruption cases, says the bureau is ramping up its ability to catch crooked politicians and might run an undercover sting on Congress.

Assistant FBI Director James Burrus called the bureau’s public corruption program “a sleeping giant that we’ve awoken,” and predicted the nation will see continued emphasis in that area “for many, many, many years to come.”

So much evidence of wrongdoing is surfacing in the nation’s capital that Burrus recently committed to adding a fourth 15- to 20-member public corruption squad to the FBI’s Washington field office.

In the past year, former Republican Reps. Duke Cunningham and Bob Ney have pleaded guilty to corruption charges. FBI agents are investigating about a dozen other members of Congress, including as many as three senators. The Justice Department also is expected to begin seeking indictments soon after a massive FBI investigation of the Alaska Legislature.

If conditions warrant, Burrus said, he wouldn’t balk at urging an undercover sting like the famed Abscam operation in the late 1970s in which a U.S. senator and six House members agreed on camera to take bribes from FBI agents posing as Arab sheikhs.

“We look for those opportunities a lot,” Burrus said, using words rarely heard at the bureau over the last quarter century. “I would do it on Capitol Hill. I would do it in any state legislature. … If we could do an undercover operation, and it would get me better evidence, I’d do it in a second.”

Philip Heymann, who oversaw the Abscam investigation as chief of the Justice Department’s Criminal Division during the Carter administration, expressed surprise to learn of the FBI’s willingness to attempt another congressional sting after the outcry from Capitol Hill over Abscam.

“It shows courage at the FBI,” said Heymann, now a criminal law professor at Harvard University. He said he concluded, after watching a recent public television documentary and listening to experts, that “there is more corruption (on Capitol Hill) than I ever thought imaginable” and that a single FBI sting “might result in very large numbers of prosecutions.”

“Operation Rainmaker,” the FBI’s broad investigation of a Washington lobbying ring, has already led to a handful of convictions, including Ney’s guilty plea last month. The inquiry was one reason for the resignation last year of House Majority Leader Tom DeLay, R-Texas, who also faces state campaign finance charges.
