The GOP has a serious leadership problem.
There hasn't been any leadership in Congress since Gingrich and Lott. As soon as the GOP got a minority they immediately started acting like the minority party, while the Democrats learned how to the the minority party over night.
It seems to be quite obvious, this political maneuver (probably White House) to put pressure on the House to make some serious concessions to pass the Senate version of the immigration bill. This is politics, plain and simple politics.
If it's true, run him out of office and let justice be done.
