Alec Baldwin defended himself today against a photographer who claims the "30 Rock" actor slugged him outside the Manhattan's city clerk's office.

"The guy lunged and he almost hit me in the teeth with the lens of the camera, so I just pushed the guy away," Baldwin told Charlie Rose. "They all scream like they're political prisoners."

Baldwin will make an appearance on "The Late Show with David Letterman" tonight. In a preview clip released before the show, Baldwin joked about the incident.

"I think you can see," he said, "I'm forming the letter 'f' with my mouth. And what I'm saying is, I said to him as I walked up to him, 'What F-stop are you on with the camera?' And he said, 'I'm on a something,' and I said, 'That's not the F-stop. … You have to set the camera on the right F-stop.'"

New York Daily News photographer Marcus Santos filed a complaint against Baldwin Tuesday and went to a hospital to be examined for injuries. Sanford Rubenstein, Santos' attorney, told ABC News that his client met with prosecutors and detectives this morning at the Manhattan District Attorney's Office and is fully cooperating with their criminal probe.

Baldwin's representative has denied that any punches were thrown and sources close to Baldwin told ABC News that the actor is keeping his options open about the possibility of filing his own assault claim.

"People think I'm just decking photographers willy-nilly. Nothing could be further from the truth," Baldwin said today. "I'm dumb, but I'm not that dumb."

Now, an associate producer for "Inside Edition" has said that her foot was run over by Baldwin's bicycle as he rode out of the lobby of his East Village apartment building this morning.

Baldwin tweeted about the crowd in front of his building, writing, "15-20 cameramen outside my bldg this am, chasing me on my bike." He later tweeted, "I am told I ran over someone's foot on my bike today. I think it was that person who placed their foot under the wheel of my bike."
