Tracy Jackson-Mark Souder's anti-abortion video

In this video, Tracy Jackson, part-time staffer to Rep. Mark Souder (R-Ind.), interviews the congressman on issues of the day as part of a series. Souder has announced his intention to resign after rumors of an affair with Jackson surfaced. He has admitted to infidelity but did not name Jackson.

Dana Milbank writes in The Washington Post:

When was it, exactly, that the Republican revolution merged with the sexual revolution?

With each passing year, the class notes for the famous House Republicans Class of '94 get more lurid. The latest entry was submitted Tuesday morning by Rep. Mark Souder (Ind.).

"I sinned against God, my wife and my family by having a mutual relationship with a part-time member of my staff," he announced in a resignation statement.

And it wasn't just any part-time staffer, according to sources in Souder's office. Five months ago, Tracy Jackson was his, er, "co-host" in a video the pair produced for his congressional Web site. The topic: abstinence education.

"You were one of the only voices in the room speaking in defense of abstinence education," Jackson, posing as interviewer, tells her alleged paramour in the video. "You've been a longtime advocate for abstinence education."
