(CNN) -- Newly elected Rep. Vance McAllister asked for forgiveness from God, his family and his constituents after a local newspaper published what it said was surveillance video of the married Louisiana Republican making out with a female staffer.
"There's no doubt I've fallen short and I'm asking for forgiveness. I'm asking for forgiveness from God, my wife, my kids, my staff, and my constituents who elected me to serve. Trust is something I know has to be earned whether your (sic) a husband, a father, or a congressman. I promise to do everything I can to earn back the trust of everyone I've disappointed," McAllister said in a statement.
"From day one, I've always tried to be an honest man. I ran for congress (sic) to make a difference and not to just be another politician. I don't want to make a political statement on this, I would just simply like to say that I'm very sorry for what I've done. While I realize I serve the public, I would appreciate the privacy given to my children as we get through this," he said.
The Ouachita Citizen in West Monroe, Louisiana, published the video it says shows McAllister and the woman passionately kissing in his office last December.
McAllister is married with five children. The woman, the paper reported, is also married.
McAllister was elected in a November special election to fill the vacancy left by GOP Rep. Rodney Alexander's resignation.
McAllister campaigned as a Christian conservative. He made headlines earlier this year when he invited "Duck Dynasty" star Willie Robertson to be his guest at the President's State of the Union address.
