More than 400 former Environment Protection Agency officials are urging the Senate to vote against Oklahoma Attorney General Scott Pruitt to lead the agency.

“Pruitt’s record and public statements strongly suggest that he does not agree with the underlying principles of our environmental laws,” wrote 447 former EPA employees. The Feb. 6 letter, organized by the Environmental Integrity Project, was sent just days after Democrats boycotted two scheduled Environment and Public Works Committee votes to advance Pruitt’s nomination to the full Senate. The boycott forced Republicans on the committee to suspend the rules on Feb. 2 so they could advance Pruitt’s nomination, 11-0, without any Democrats. Democrats wanted more information from Pruitt.
