During Lawrence O'Donnell's signature "Rewrite" segment, the MSNBC host challenged Mitt Romney's oldest son, Tagg, to what sounded like a straight up, bare-knuckle bar fight.
O'Donnell replayed a radio interview with Tagg, in which Romey's son joked about wanting to "take a swing" at the president for calling his dad a liar during Tuesday night's debate.
O'Donnell was not happy, and challenged Tagg on his comments. "When I hear you talk about taking a swing and taking punches, why do I get the feeling that you've never actually taken a punch or thrown a punch?" O'Donnell asked.
"I didn't have that luxury in the part of Boston that I grew up in, but in your rich, suburban, Boston life, with your father filling a $100 million trust fund for you, I dont' know, I just get the feeling that things were kind of different."
He added, "You're mad at President Obama for calling your father a liar? Well, let's get something straight. He didn't call your father a liar, I did. The president just said that what your father said isn't true. I've been saying it all year that your father is a liar. I've repeatedly said that your father lies and is trying to lie his way into the White House."
He then challenged Tagg further. "So you want to take a swing at someone for calling your old man a liar? Take a swing at me," O'Donnell said. "Come on, come on...I'll make it easy for you. I'll come to you...Go ahead, Taggard. Take your best shot."
O'Donnell also defended "View" co-host Whoopi Goldberg for asking Ann Romney if her husband and sons did not serve in the armed forces for religious reasons.
Romney said that her husband was "serving his mission" during Vietnam, so did not enlist, but it was not against their religion to serve.
"When Romneymen reach military age, they bravely go out into the world and try to convert people to Mormonism," O'Donnell said, his tone dripping with mockery.
He added, "Whoopi Goldberg was closer to the truth than Ann Romney acknowledged," O'Donnell said. "Ann Romney is right that serving in the military is not against the Romney family religion, but the complete truth includes the fact that young, Mormon men were allowed to use a special deferment that no one else was allowed to use."
