Prosecutors charged a top congressional staffer Wednesday with filing a false security clearance form nearly a year after he pled guilty to failing to pay taxes, officials said. The Justice Department alleges that Isaac Lanier Avant, chief of staff to Rep. Bennie Thompson (D-Miss.) and Democratic staff director for the Homeland Security Committee, “willfully made a false statement” on security clearance forms in 2008 and 2013, officials said in a news release.
