WASHINGTON (AP) — The White House will withdraw the nomination of a gun-control advocate to lead the Bureau of Alcohol, Tobacco, Firearms and Explosives after David Chipman ran into bipartisan opposition in the Senate. That word comes from a person familiar with the decision. Chipman is a former federal agent and adviser at the gun control group Giffords. He won praise from advocates for his work pushing for greater regulation and enforcement on ghost guns, overhauling the background check system and moves to reduce the trafficking of illegal firearms. But that same advocacy drew opposition from some moderate Republicans in the Senate as well as independent Angus King. That opposition doomed Chipman’s prospects for confirmation.
