Senate Democrats are planning an all-night talkathon Thursday over President Trump's pick to lead the Environmental Protection Agency (EPA).

The late-night floor drama comes after senators voted to move forward with Scott Pruitt's nomination earlier Thursday in a 54-46 vote.

A final vote, absent a deal, is expected early Friday afternoon.

Democrats don't have the manpower to block Pruitt on their own. Cabinet nominees only need a simple majority, and Republicans have 52 seats.

Democrats blasted McConnell on Thursday for refusing to delay a vote on Pruitt. They wanted more time to wait for records from his time as Oklahoma attorney general requested more than two years ago.

The Center for Media and Democracy had sought, under Oklahoma’s state records law, copies of emails between Pruitt’s staff and representatives of various fossil fuel and conservative interests.

Eleven Democrats had already taken to the floor as of Thursday afternoon to protest Pruitt's nomination.
