“While reportedly under investigation for her ties to an influential pro-Israel lobbying organization, California Rep. Jane Harman last month hosted a private dinner for the group that was attended by two top Bush administration officials -- Director of National Intelligence John Negroponte and Secretary of Homeland Security Michael Chertoff.
"The Sept. 13 dinner took place at the home of Harman, the ranking Democrat on the House Select Committee on Intelligence, and was attended by over 120 top financial backers of the American Israel Public Affairs Committee (AIPAC). The highlight of the evening was a panel discussion in which Harman played the host, questioning Negroponte and Chertoff about Mideast developments, international terrorism and homeland-security issues, according to an AIPAC official.” 
Why was California Rep. Jane Harman being investigated?
“The FBI has been looking into claims since mid-2005 that Harman of California, the top Democrat on the House Permanent Select Committee on Intelligence, made explicit pledges to the American Israel Public Affairs Committee, AIPAC, in exchange for the group's support in her quest to keep her spot on the intelligence panel.
"The Washington Post reports one of those pledges was that for AIPAC's help, she would ask Republican administration officials to ease up on a probe of two former AIPAC lobbyists charged with violating the Espionage Act by receiving national defense information and transmitting it to journalists and Israeli Embassy employees. News of the FBI's investigation first appeared Friday in Time magazine.”
