WASHINGTON -- A Republican congressman from Georgia is standing by comments that he fears President-elect Barack Obama could be planning to build a domestic security force so that he can impose a Marxist dictatorship.

Rep. Paul Broun had sent mixed signals on Tuesday about retracting his comments, saying in a radio interview that he regretted the way they have been perceived while at the same time issuing a written statement defending them.

But spokeswoman Jessica Morris said Wednesday the congressman is "not taking back anything he said."

In an interview with The Associated Press Monday, Broun pointed to a speech Obama made in July in which he called for a large new civilian security force. Broun compared the proposal to security forces in Nazi Germany and said he was concerned that Obama could be planning something similar.
