Sen. Johnson warns Boehner could lose speakership over agreeing to tax hikes

"I don't quite honestly believe that Speaker Boehner would be Speaker if that happens. I think he would lose his speakership," Johnson said in an interview with Fox News released Monday.

Senate Democrats and Republicans are preparing two separate bills to replace the sequester, which would impose $85 billion in spending cuts on the government on March 1. Neither is expected to be approved, and both parties seem intent on setting the other up for blame over the cuts.

Although in the last few months Boehner has, at times, faced a few legislative backfires and frustrations, his hold on the speaker's office office seems secure. Boehner was reelected Speaker in early January with nine Republicans voting other Republicans and a few others voting present.
