Sen. Bob Corker, R-Tenn., told reporters Thursday morning that comprehensive immigration reform and serious entitlement reform were both dead for the year in the Senate. He blamed President Obama and Senate Democratic leaders for creating a toxic atmosphere and refusing to negotiate with Republicans, like him, willing to work on a compromise.

Asked about tax reform at a press breakfast hosted by the Christian Science Monitor, Corker said: "I see no way it is going to be dealt with this year. In fact, I see no way anything important is going to be dealt with this year."

He said "GSE reform" -- meaning government-sponsored enterprises like Fannie Mae and Freddie Mac -- was the only possible exception.

"Tax reform certainly is not going to happen this year. I don't think immigration is going to happen this year," Corker said.

The senator said the problem was that President Obama's administration "was never serious" about actually reaching a deal, at least as far as tax reform went. The meetings with Republican lawmakers were just "optics" so they could claim they were trying and then blame the failure on the GOP.

"This president is afraid of his [political] base. He is not willing to take on his base and stretch it until he can actually reach an accommodation with the other side," Corker said.
