President Joe Biden’s nominee to lead the Environmental Protection Agency’s air office gained Senate confirmation Wednesday after his nomination was held in limbo for almost two years.

Joseph Goffman, the White House’s pick to be an assistant administrator for the EPA, passed on a close vote of 50-49. Sen. Joe Manchin (D-WV) voted with Republicans against the nominee. Sen. John Barrasso (R-WY), whose wife recently died, did not vote.
