"It is time for Congress to act. But I believe the House has its job to do, and we will do our job."
"I will say to you, the House will in fact act," he said.
It's worth clarifying the context. Last year, when Boehner vowed that the Republican-led House will "act," he meant he and his colleagues were finally going to do something about the broken immigration system. This morning, when Boehner vowed that the Republican-led House will "act," he meant GOP lawmakers intend to stop President Obama from doing something about the broken immigration system.
The point, however, is that there's a challenge in taking the House Speaker seriously. Last year, he vowed that he and his members will do their job on immigration reform, and then Boehner broke his word. Now the Speaker is vowing to take on the president -- somehow, in some way, in reference to some policy dispute -- and given recent history, one would be forgiven for thinking, "We've heard this talk before."
There's an inherent problem when leaders lack credibility. Remember when Boehner said Republicans wouldn't pass a clean debt-ceiling increase? What the Speaker vowed would happen and what actually happened turned out to be very different things. Remember when Boehner said Republicans wouldn't shut down the government? The same dynamic unfolded.
Of course, there's also the issue of timing.
