In a letter to Senate Judiciary Committee Chairman Patrick Leahy (D-Vt.) and ranking member Chuck Grassley (R-Iowa), Begich urged the lawmakers to hold a hearing to advance the nomination of acting ATF Director B. Todd Jones.
Begich is up for reelection in 2014 in a state that votes heavily Republican and has a high level of gun ownership.
Some Democrats have accused the National Riffle Association (NRA) of using its lobbying power to prevent the advancement of an official director in order to ensure gun laws are not properly enforced.
In April, the Senate tried to pass a comprehensive gun control bill to require background checks on all gun sales, but the measure failed to get the 60 votes needed to overcome a Republican filibuster. Begich voted against the background check measure.
Begich told Leahy and Grassley that he would support the nomination of Jones if he were to make it to the Senate floor for a confirmation vote.
“I am inclined to support his nomination based on not only the urgent need for leadership, but on his record as a public servant who works with both political parties to ensure public safety while respecting the Second Amendment rights of law-abiding Americans,” the letter stated.
