Sen. Susan Collins (R-ME) made clear she will not be supporting Biden’s nominee, David Chipmam to head the ATF.

“I am concerned that his confirmation would do significant damage to the collaborative working relationship that must exist between ATF, the firearms industry, sportsmen and women, and other law-abiding gun owners exercising their Second Amendment rights,” Collins said.

Collins’ remarks appear to signal Republican unity against Chapman’s nomination in the Senate chamber.
