Sarah Palin is now calling for President Barack Obama's impeachment.
In a column published on Breitbart.com Tuesday, Palin accused the president of "purposeful dereliction of duty," likening Obama's treatment of the United States to that of an abusive spouse.
"Enough is enough of the years of abuse from this president," Palin, the former governor of Alaska and 2008 GOP vice presidential candidate, wrote. "His unsecured border crisis is the last straw that makes the battered wife say, 'no mas.'"
Palin suggested that the president has deliberately left the U.S.-Mexico border unsecured, echoing a similar theory floated by Texas Gov. Rick Perry (R) earlier this week.
"Without borders, there is no nation," Palin wrote. "Obama knows this. Opening our borders to a flood of illegal immigrants is deliberate. This is his fundamental transformation of America. It’s the only promise he has kept."
On Tuesday, Obama requested $3.7 billion from Congress to address the situation at the border. The funds would help improve security at the border in addition to providing care for the children who have come into the Department of Health and Human Services' custody.
Palin, who last year suggested that Obama could be impeached over the debt limit, argued in the Tuesday column that Obama's "rewarding of lawlessness" had caused "irreparable harm."
"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. "The many impeachable offenses of Barack Obama can no longer be ignored. If after all this he’s not impeachable, then no one is."
Sen. John McCain (R-Ariz.), who ran for president in 2008 with Palin as his running mate, didn't have much to say about her call for Obama's impeachment.
"I always respect other people's opinions," McCain told The Huffington Post during a hallway interview at the Capitol.
The Arizona senator said he hadn't read Palin's column yet and hedged on making any judgments about it before reading it. Still, he distanced himself from her stance.
"Am I proposing that the president be impeached? No," he said.
This post has been updated to include McCain's remarks.
