At an event in Chicago last week, Warren slammed Republicans' efforts to repeal Obamacare. She said they want a more "brutal" health care bill.
She said the GOP's first effort at passing a health care bill failed because it "was not brutal enough for a big chunk of the Republican party."
"God, what planet do they live on," she said.
She then joked, "I hope they leave their bodies to science. I would like to cut them open."
Mouthing the word "heart," she gestured that she wanted to know if they had hearts, suggesting that the Republicans' demands for a more "brutal" bill were heartless.
