At a deposition earlier this month, Susan Ralston, the former executive assistant to Karl Rove, responded to questions in a number of areas but would not answer questions about White House contacts with convicted lobbyist Jack Abramoff and her lawyer said Ms. Ralston would assert her Fifth Amendment privilege if compelled to testify. In a memo, Chairman Waxman explains the Committee will seek testimony from Mr. Abramoff’s former lobbying associates and former and current Administration officials before considering Ms. Ralston’s request for immunity.
