Clinton made the move shortly before leaving her podium as host MSNBC cut to a commercial break.

The pause in the debate came after a heated exchange between the two White House contenders.

Sanders has criticized Clinton for her ties to Wall Street and for accepting speaking fees from banks. The former secretary of State hit back at that, saying that Sanders was unfairly suggesting she was bought by corporate interests.

“It’s time to end the artful smear that you and your campaign have been carrying out in recent weeks, and let’s talk about the issues that divide us,” Clinton said to the Vermont senator.

Her remarks drew boos from some in the crowd.

The MSNBC debate took place in Durham, N.H. It’s Clinton and Sanders's first debate against each other without other candidates on stage. It's also their last debate before New Hampshire voters hit the polls on Tuesday.
