In January 2012, Dent co-sponsored the Enemy Expatriation Act with Senator Joe Lieberman. The bill's purpose was "To add engaging in or supporting hostilities against the United States to the list of acts for which United States nationals would lose their nationality," where the term "hostilities" means any conflict subject to the laws of war. The proposal would allow the United States government to strip U.S. citizens of their citizenship without requiring that the citizen have been convicted of a crime.
