Dozens of House Republicans are urging the Senate to oppose the confirmation of David Chipman, President Joe Biden’s pick to helm the Bureau of Alcohol, Tobacco, Firearms, and Explosives, who served as an adviser to a prominent pro-gun control group. Indiana Rep. Jim Banks and 68 of his GOP colleagues wrote a letter, obtained by the Washington Examiner, on Monday to Senate Majority Leader Chuck Schumer and Senate Minority Leader Mitch McConnell, urging them to reject the nomination of Chipman, a former senior policy adviser for Giffords, an outspoken firearms reform group. Biden selected the 25-year ATF special agent for the post during a wave of gun control executive orders on April 7.
