Senate Democrats are planning to once again stage a series of overnight speeches on the Senate floor, this time in opposition to Oklahoma Attorney General Scott Pruitt’s nomination to head the EPA.

“We intend to stand our ground,” said Delaware Sen. Thomas R. Carper, the ranking Democrat on the Environment and Public Works Committee. While Pruitt appears poised for confirmation, Carper said Democrats were not going quietly into the night.

“[If] we go home, we go to bed, say, ‘That’s it, we fought the good fight, it’s 10 o’clock, we’re going to call it a day,’ there’s zero chance we prevail,” Carper said.

Carper was joined by fellow Democrats Sheldon Whitehouse of Rhode Island, Edward J. Markey of Massachusetts, Jeff Merkley of Oregon and Tammy Duckworth of Illinois at a Thursday press conference to criticize Republican leadership for not delaying Pruitt’s confirmation.
