A dozen House Republicans have cosponsored a resolution to impeach Joe Biden’s ATF nominee, David Chipman, even before he’s confirmed by the Senate.

The move was led by Rep. Matt Rosendale, R-Mont.

It has 11 other co-sponsors in addition to Rosendale: Reps. Bob Good, R-Va.; Jeff Duncan, R-S.C.; Marjorie Taylor Greene, R-Ga.; Ralph Norman, R-S.C.; Jody Hice, R-Ga.; Diana Harshbarger, R-Tenn.; Scott Perry, R-Pa.; Alex Mooney, R-W.Va.; Andy Harris, R-Md.; Paul Gosar, R-Ariz.; and Andrew Clyde, R-Ga.

“The confirmation of David Chipman to the ATF would be a direct threat to the Second Amendment rights of Americans and the rule of law,” Rep. Rosendale said in a statement. “Not only has Chipman previously given false testimony to Congress, but his statements on gun-control are evidence that his confirmation would be a failure to support and defend our constitutional rights. If appointed, both are impeachable offenses and worthy of Congress to consider his removal.”

After serving 25 years in the ATF, Chipman became a paid policy consultant for two anti-gun groups, Everytown and then Giffords, where he works now.

He has called for a ban on America’s most popular rifle, and has said that people who fail a NICS background check should be prosecuted.
