Rep. Paul Broun is sorry for seemingly comparing Obama to Adolf Hitler.

(CNN) - Republican Paul Broun is sorry for calling President-elect Barack Obama a 'Marxist' and comparing him to Adolf Hitler, the Georgia Congressman said Tuesday.

“I regret putting it that way,” he told WGAC radio in Augusta, according to the Atlanta Journal Constitution. “I apologize to anyone who has taken offense at that.”

In an interview with the Associated Press earlier this week, Broun admitted to calling the future commander-in-chief a 'Marxist' at a recent Rotary club meeting, and said Obama has expressed support for policies similar to those of Hitler.

"It may sound a bit crazy and off base, but the thing is, he's the one who proposed this national security force," Broun told the AP. "I'm just trying to bring attention to the fact that we may– may not, I hope not - but we may have a problem with that type of philosophy of radical socialism or Marxism."

Broun was specifically referring to a July speech by Obama, where the then-Democratic presidential nominee said he supports a civilian force helping the military when it comes to national security: "We've got to have a civilian national security force that's just as powerful, just as strong, just as well funded [as the military]," Obama said in the speech that was largely a call to national service.

Responding to those comments, Broun told the AP Monday: "That's exactly what Hitler did in Nazi Germany and it's exactly what the Soviet Union did. When he's proposing to have a national security force that's answering to him, that is as strong as the U.S. military, he's showing me signs of being Marxist."

"We can't be lulled into complacency," Broun added. "You have to remember that Adolf Hitler was elected in a democratic Germany. I'm not comparing him to Adolf Hitler. What I'm saying is there is the potential."

The Obama transition office did not respond to Broun's comments, and in his interview Tuesday to WGAC, the first term congressman said, “The point I tried to make is that he is extremely liberal, he has promoted a lot of socialistic ideas, and it just makes me concerned."
