"Senator [Tom] Cotton has campaigned on wanting to kill Obamacare. He voted to repeal the Affordable Care Act back in January, but he now says, despite these marathon all-night sessions going on in the House, Republicans need to do better, they need to start over, they need to come up with something that the Senate says will actually reduce prices for insurance and keep it affordable."

Two committees in the house were up all night long trying to get a version of the repeal of the Affordable Care Act passed. House Republicans are just fighting tooth and nail to pass it in the House, to try to get it into the Senate, to try to make it then so that the Senate will get on board. But you know who one of the Republican senators is who`s not on board with this anymore? Senator Tom Cotton.
