Video of the Day: Gay Rights Protest at Gingrich Event Gets Physical

Forget "Minnesota nice": not only is the state a hotbed of hecklers, one speech attendee got aggressive in squelching a protest.

Minnesota -- a mostly blue state that sometimes elects Republicans -- is proving to be treacherous territory for GOP presidential candidates. It seems they can barely set foot in the state without being targeted by activists of various stripes, usually advocating for gay rights. Both Rick Santorum and Michele Bachmann were "glitter bombed" earlier in the campaign, and Mitt Romney got the treatment last week, though he skillfully played it off as celebration for his Florida primary win. And Tuesday morning in Bloomington, Minn., gay-rights activists heckled Newt Gingrich as he gave a speech.

As the video shows, things got a bit nasty. After one heckler was escorted out of the room, another stood up and took over. Before police could get to the second protester, a member of the audience took matters into her own hands, giving the heckler a solid shove and waving her fist while pointing out of the room.

Meanwhile, Rep. Ron Paul was glitter bombed Monday night in Minneapolis.
