The staff member who has been accused of leaking the security footage of married Rep. Vance McAllister (R-La.) apparently kissing another staffer has resigned.

The Monroe News-Star reports that McAllister's office says Leah Gordon left of her own accord:

Adam Terry, McAllister’s chief of staff, confirmed her resignation late Wednesday. He said Gordon wasn’t fired.

“We won’t terminate or discipline any employee until after our internal investigation of the security breach is complete,” Terry said. “(Gordon) resigned on her own.”

McAllister, R-Swartz, has been under fire since a video was published last week showing the married congressman kissing former married staffer Melissa Peacock, who has since resigned.

Last week prominent West Monroe minister Danny Chance said he has proof that it was Gordon, who also worked for former U.S. Rep. Rodney Alexander, R-Ruston, who had possession of the video.

Gordon also worked for state Sen. Neil Riser’s campaign when he ran against McAllister last fall, but McAllister kept her on staff after winning the election.

Chance wouldn’t reveal his sources, but he said he was willing to produce witnesses in court if needed.

McAllister is still facing pressure to resign, including from Gov. Bobby Jindal (R) and state GOP Chairman Roger Villere. He has thus far resisted those calls.

In a video obtained by "The Ouachita Citizen," Rep. Vance McAllister (R-La.) is allegedly seen kissing a female member of his district office staff last December. The congressman has since issued an apology saying, "There's no doubt I've fallen short and I'm asking for forgiveness." (The Ouachita Citizen)
