Will House Republican leaders bring up immigration reform after their primary season is over? Conservatives aggressively oppose the idea.

While they acknowledged Wednesday that there were rumors to that effect, they warned Republicans would severely damage their relationship with their constituents if that strategy is tried.

"When there is the rumor that immigration is going to be worked on after the filing deadline for primaries, everybody believes that at home. Because they think that the establishment, K Street, is going to pull that stunt because they don't trust them," Rep. Tim Huelskamp, R-Kan., told the Washington Examiner.

Rep. Raul Labrador, R-Idaho, explicitly warned against the idea.

"There better not be," he said, when asked by the Washington Examiner about the rumored strategy. "I think that's offensive to the American people, that after the primary season is over, we're actually going to have to, you know, sell immigration reform."

Labrador suggested that if Republicans truly believed in immigration reform, they should do it without hiding from voters.

The best time to address the issue, he suggested, was in 2015, once Republicans took back the Senate.

"It's early enough that it doesn't become a presidential campaign issue, but also early enough that constituents will know exactly where we stand," Labrador said.
