Daily Caller:

House Republican leaders told Rep. Joe Barton that he would be stripped of his ranking member status on a key committee Thursday if he did not immediately apologize for comments earlier in the day accusing President Obama of a “shakedown” of oil giant BP, sources told the Daily Caller.
“He was told, ‘Apologize, immediately. Or you will lose your position, immediately,” a House GOP leadership aide said, describing a meeting between Barton and House Minority Leader John Boehner and House Minority Whip Eric Cantor.
“Now that he has apologized, we’ll see what happens going forward,” the GOP aide said.
