A top official at Immigration and Customs Enforcement has resigned following allegations by several subordinates of lewd behavior.

ICE Chief of Staff Suzanne Barr submitted her resignation in a letter, obtained by FoxNews.com, to ICE Director John Morton. She rejected the allegations against her as “unfounded” but said she didn’t want to distract from the agency’s mission.

“In recent weeks, I have been the focus of unfounded allegations designed to destroy my reputation, but of greater concern however, is the threat these allegations represent to the reputation of this agency and the men and women who proudly serve their country by advancing ICE’s mission,” Barr wrote.
