The United States House Committee on Ethics started researching the complaint on July 17, 2012, and decided on August 31 that it would proceed with an investigation. On March 19, 2013, the Committee declared that a special panel would examine whether Andrews's travel expenses from the Edinburgh and California trips complied with campaign finance laws. Andrews resigned from Congress on February 4, 2014. He said that the campaign finance probe had "no role at all" in his resignation, and that he was departing for a position at the Dilworth Paxson law firm. The FEC dismissed the complaint on June 3, 2014 with "prosecutorial discretion", noting that Andrews reimbursed his campaign for the Edinburgh trip before he received the complaint, and that any violations in the California trips were "relatively small".
