Rep. Michele Bachmann (R-Minn.) and Sen. Bernie Sanders (I-Vt.) got into a heated debate during a Monday appearance on CNN's "The Situation Room."

When Sanders said Republicans -- including Bachmann -- want to cut social security, Bachmann shot back by saying the claim was "absolutely a lie."

“This is the old canard that is trotted out all the time. It’s a lie, let’s face it Sen. Sanders, you shouldn’t be lying about what our position is," Bachmann said.

The two also discussed education, the minimum wage and Wall Street regulations.
