The book states Geithner and the Treasury Department ignored a March 2009 order to consider dissolving banking giant Citigroup while continuing stress tests on banks, which were burdened with toxic mortgage assets.

In the book, Obama does not deny Suskind’s account, but does not reveal what he told Geithner when he found out. “Agitated may be too strong a word,” Suskind quotes Obama as saying. Obama says later in the book that he was trying to be decisive but “the speed with which the bureaucracy could exercise my decision was slower than I wanted.”

Geithner says in the book that he did not recall that Obama was mad at him about the Citigroup decision and rejected allegations contained in White House documents that his department had been slow to enact the president’s plans.

“I don’t slow walk the president on anything,” Geithner told Suskind.
