Sen. Ron Johnson (R-Wis.) said House Speaker John Boehner (R-Ohio) would lose his speakership if he agrees to new tax revenues to avert the across-the-board spending cuts that are set to kick in on March 1.

"I don't quite honestly think that Speaker Boehner would be speaker if that happens," Johnson told Fox News of Boehner caving on taxes as part of a sequester replacement package. "I think he would lose his speakership."
