Sarah Palin said Vice President Biden’s terrorist remarks “appalling” and “vile.”

Vice President Biden was criticized Monday over reports of a private meeting he had with House Democrats in which Tea Party Republicans were compared to “terrorists,” though Biden denies he described Republicans that way.

A senior Democratic official told Fox News that Biden made such comments in reaction to a heated conversation with liberal House members like Rep. Mike Doyle, D-Pa., who were venting that Republicans got too much out of the debt ceiling deal unveiled the night before and “acted like terrorists.”

The comment drew an immediate rebuke from Sen. Rand Paul, R-Ky., one of the most outspoken Tea Party-aligned lawmakers in Congress.

“With the president holding the American economy hostage, I would prefer to think of myself as a Freedom Fighter,” Paul said in a statement, calling the remarks “insulting.”
