Chris Cilizza writes in the WaPo:
Republicans continue to grow more bold in their criticism of Geithner. Georgia Sen. Johnny Isakson said that he would resign if he were in Geithner's shoes and Kentucky Sen. Jim Bunning alleged that the treasury secretary "has an incestuous relationship with Wall Street" in an interview on the Fox Business Network.
Even some Democrats -- privately, of course -- are beginning to grumble that Geithner's time may be up. "His position is not sustainable," said one senior Democratic strategist. "It's clear he knew and approved of bonuses that the White House now thoroughly condemns."
