Susan Ralston, ex-employee of Seattle's Preston Gates and Ellis law firm, has been summoned to appear before a Congressional committee next week to discuss her former boss, Jack Abramoff, and face questions about the Lobbygate figure's access to the White House. She's also likely to be asked about her other former boss, Karl Rove. Ralston, who was Abramoff's personal assistant at Preston Gates (now K&L Gates), left the law firm (as did Abramoff) in 2001 and became Rove's assistant. Now Rep. Henry Waxman wants to ask her about thousands of dollars in gifts she received during her White House days from Abramoff; Ralston resigned last Fall after that arrangement was disclosed publicly. Waxman's Oversight and Government Reform Committee says it wants to take Ralston's deposition as "part of the Committee's investigation, begun last spring, into lobbying contacts between lobbyist Jack Abramoff and the White House."
