WASHINGTON — House Republicans began the new Congress with old divisions on display Wednesday, bitter fallout from a failed rebellion against Speaker John Boehner.

Boehner took swift action against two of the dissenters, knocking them from a key committee. But some of his allies demanded more, furious at the two dozen lawmakers who opposed the Ohioan in Tuesday’s speaker vote. In the process, the GOP is starting the year with party infighting instead of a unified challenge to President Barack Obama.

“All of us think that they should have retribution,” Boehner loyalist Devin Nunes of California said of the rebels. “They put the conservative agenda at risk with their wanting to be on television and radio.”

The dissidents warned of their own payback if Boehner does take further steps against them.

“There’s going to be a fight,” said Rep. Louie Gohmert, R-Texas, when asked what would happen if leaders retaliated against lawmakers who opposed Boehner’s re-election. “And it’s going to be real hard to bring the party together like they say they want to do.”
