Feb. 6 (Bloomberg) — House Speaker John Boehner said Thursday it will be difficult to pass an immigration bill because fellow Republicans don't trust President Barack Obama to implement the law, a position that diminishes chances for House action this year.

"There's widespread doubt about whether this administration can be trusted to enforce our laws," Boehner told reporters in Washington. "It's going to be difficult to move any immigration legislation until that changes."

While Boehner tries to shift blame to Obama, many House Republicans are wary of engaging in a policy debate that divides the party and risks overshadowing their focus on criticizing the president's health-care law.
