WASHINGTON (December 2, 2012)--House Speaker John Boehner said Sunday he was "flabbergasted" when Treasury Secretary Tim Geithner pitched the White House plan to save the nation from the "fiscal cliff."

Boehner told "Fox News Sunday" that after Geithner briefed him privately Thursday, he looked at Geithner and said, "You can't be serious."

Boehner called it "silliness" that the White House was, among other things, asking Congress to give up its power to set the nation's debt limit.

President Barack Obama's plan calls for $1.6 trillion in higher taxes over the next decade.

Boehner, R-Ohio, said he's willing to rethink tax deductions for the wealthiest Americans, but declined to provide further specifics. The White House says the GOP tax proposals so far wouldn't pull in as much revenue as they claim.
