(CNN) -

Rep. Vance McAllister said Monday he will run for re-election in November despite previously announcing he would not seek another term in Louisiana's 5th Congressional District.

McAllister - who is married with children - was caught on video kissing an aide in his office, sparking calls for the Republican congressman to step down. Three weeks after the video was posted by a local newspaper, he announced he would not seek re-election, only to reverse that decision on Monday.

"Today, after consulting with my wife and family, I have made a decision to run for re-election for the 5th Congressional District," he said in statement. "I know the needs of this congressional district very well. I also know that this district needs a strong, conservative voice in Congress."

He is scheduled to speak at a news conference in Monroe, Louisiana, later Monday.

Just over two months ago, McAllister announced he wouldn't run again in the fall, apologizing for his actions after a local newspaper published a surveillance video of the Louisiana congressman passionately kissing his scheduler in his office last December.

McAllister, who campaigned as a Christian conservative, was elected in a November 2013 special election to fill the vacancy left by GOP Rep. Rodney Alexander's resignation. Gov. Bobby Jindal and the state's Republican Party urged the embattled lawmaker to resign after the video surfaced, citing McAllister's infidelity as an example of a well-worn hypocrisy in politics.

Louisiana's 5th Congressional District is located in the northeast portion of the state and is considered safe for the GOP.
