Rep. Jane Harman , the California Democrat with a longtime involvement in intelligence issues, was overheard on an NSA wiretap telling a suspected Israeli agent that she would lobby the Justice Department reduce espionage-related charges against two officials of the American Israeli Public Affairs Committee, the most powerful pro-Israel organization in Washington.

Harman was recorded saying she would "waddle into" the AIPAC case "if you think it'll make a difference," according to two former senior national security officials familiar with the NSA transcript.

In exchange for Harman's help, the sources said, the suspected Israeli agent pledged to help lobby Nancy Pelosi , D-Calif., then-House minority leader, to appoint Harman chair of the Intelligence Committee after the 2006 elections, which the Democrats were heavily favored to win.

And that, contrary to reports that the Harman investigation was dropped for "lack of evidence," it was Alberto R. Gonzales, President Bush's top counsel and then attorney general, who intervened to stop the Harman probe.

Why? Because, according to three top former national security officials, Gonzales wanted Harman to be able to help defend the administration's warrantless wiretapping program, which was about break in The New York Times and engulf the White House.

As for there being "no evidence" to support the FBI probe, a source with first-hand knowledge of the wiretaps called that "bull****."

According to two officials privy to the events, Gonzales said he "needed Jane" to help support the administration's warrantless wiretapping program, which was about to be exposed by the New York Times.
