Former Alaska Gov. Sarah Palin called on Congress this week to impeach President Obama, citing the White House’s underwhelming response to the immigration crisis on the U.S.-Mexico border as reason enough to end his “lawless” presidency.

“It’s time to impeach; and on behalf of American workers and legal immigrants of all backgrounds, we should vehemently oppose any politician on the left or right who would hesitate in voting for articles of impeachment,” Palin wrote in an op-ed published Tuesday.
