U.S. Sen. Michael Bennet took to the Senate floor Thursday morning to lambaste the GOP’s health care bill and, in a booming voice, said that President Donald Trump has “no idea or interest” what’s in the proposed legislation.

“Every single person here knows that!” the Colorado Democrat yelled.

The Senate is working through the Republican health care bill, with an expected flurry of amendments Thursday called a “vote-a-rama.”

“This process is a disgrace,” Bennet said. “… The end product, whether we pass this bill or whether we don’t, is not going to improve health care for the people we represent.”
