Palin on Tuesday said that Americans "should vehemently oppose any politician on the left or right who would hesitate in voting for articles of impeachment."
Holder blamed "gridlocked Washington" on Republicans.
“For whatever reason, [some] Republicans decided early on that this was a president they were just simply not going to cooperate with,” he said. "And over the past five-and-a-half years, we have seen demonstrations of that, where the president has reached out his hand, offered compromises that have simply not been met [in the way] they have been in the past by a Republican Party willing to do the appropriate things."
He said he doesn't think that Republicans' lawsuit against Obama is "going to have legs."
The Attorney General also rejected calls by Republicans for his own impeachment. He said that a special prosecutor to investigate the IRS scandal was unnecessary.
