(FOX NEWS) Fresh off a series of weekend victories in state caucuses, Bernie Sanders turned up the heat on Hillary Clinton at Sunday’s debate in Flint, Mich., sharply challenging her economic credentials and suggesting her gun control stand would ban guns in America. But the Democratic front-runner fought back, blasting him for voting against the auto bailout, dismissing him as a “one-issue candidate” and hitting him once again for his stance on guns.

The Vermont senator reached back to the 1990s as he went after Clinton’s support for “disastrous trade agreements” like NAFTA. His rhetoric was notably more pointed and, reflecting the tension in the race, Sanders even cut her off at times as she tried to speak over him.

“Excuse me, I’m talking,” Sanders snapped, during one feisty exchange on the economy.
