Speaker John Boehner (R-Ohio) on Thursday told President Obama and Senate Democratic leaders he was calling their bluff after they threatened to kill the backup tax plan he has promised to push through the House.

“I am not convinced at all that when the bill passes the House today that it will die in the Senate,” Boehner said at a midday press conference in the Capitol. “At some point the Senate has to act.”

With 11 days to go before large tax hikes and spending cuts kick in, the House on Thursday evening will vote on legislation that prevents part of the “fiscal cliff” by making permanent tax rates on income up to $1 million while allowing rates to go up for taxpayers earning more.

Senate Majority Leader Harry Reid (D-Nev.) has said the upper chamber won’t even vote on the bill, and he said the Senate will recess for Christmas on Saturday. The Senate earlier this year approved legislation that extends tax rates for annual family income up to $250,000, but it has not passed the House.
