developments on that congressman caught kissing a staffer on camera. This morning, the staffer is out of a job. And the congressman's office may be asking the FBI to launch an investigation into who leaked the tape. ABC's Jeff Zeleny has the story. Reporter: This morning, congressman Vance Mcallister under fire. And firing back. After this surveillance video surfaced, showing the married Louisiana republican kissing a married scheduler in his office. Overnight, aides to the congressman telling ABC news, they may ask the FBI to investigate how the video was leaked. Good morning. Reporter: Republican leaders, keeping their distance. The American people deserve all of their representatives here in Washington to hold to a very high standard of behavior and conduct. Reporter: As for the scheduler, Melissa peacock, seen here in the congressman's arms, she's resigned. Melissa's husband, Keith, speaking out for the first time about that kiss. Keith peacock, a long-time family friend who donated over $5,000 to the Mcallister campaign, told "Inside edition" he is devastated that the congressman ruined his life. Peacock added, Mcallister is about the most nonreligious person I know. But the congressman is vowing to run for re-election in November. We stopped around Tuesday. But we were told he wasn't around. After running to promote Christian values -- I believe values like faith, family and hard work, are sorely missing in Washington, D.C. Reporter: He told us when he arrived here nearly five months ago, he was focused on working, not playing hard. We're up here to work, not to socialize. It seems like there's a lot of it that goes on. Reporter: Now, Mcallister could face an ethics investigation because the woman he was kissing worked in his office. While the congressman is trying to figure out who leaked this videotape, politically speaking, it may not matter. These families were long-time friends. So, in addition to the scandal unfolding here in Washington, there is a family drama in Louisiana that's even more painful and complicated. Lara? I'll say. Jeff, thank you very much.
