ATLANTA , Georgia ( CNN ) -- A Georgia congressman said Wednesday he 's received death threats and found Nazi graffiti outside his office in the aftermath of heated protests about health care reform . Rep. David Scott 's staff found a swastika on a sign outside his district office in Georgia . David Scott , a Democrat from north-central Georgia , told CNN he has received several offensive faxes and letters , including some with death threats and racial abuse . Scott is black .

The congressman showed CNN a cartoon of Barack Obama , depicting the president as a clown with a swastika on his head , which Scott said he had received in the mail . Tuesday , his staff found a swastika painted over Scott 's name on a sign outside his office . `` I was just simply appalled , '' he said . `` This symbol represents the most heinous period in world history , indicative of man 's greatest inhumanity to man , where nearly 6 million Jewish people and others were murdered purposely by Adolf Hitler , '' Scott said . `` So when you reach that point ... this is very , very dangerous . '' Local police and the F.B.I . are investigating . Scott said he believes the swastika and hate mail are a result of the acrimonious health care debate .

This is America , it 's rough and tumble , that 's what we 're here for , but this is something else , '' he said . `` This is not good for America , not good for this debate , it 's a distraction , '' the congressman said . And he says Obama should call for an end to it . `` I think he really has to speak strongly ... before somebody gets hurt at one of these things . '' Another congressman , Washington state Democrat Brian Baird , has canceled public meetings after saying he 's received death threats . CNN 's T.J.
