Farrakhan spoke Wednesday on Chicago radio station WVON and pointed specifically to derisive comments, including the "N-word," shouted at legislators who supported Obama's health care legislation as reason to fear for Barack Obama.
He also pointed to rallies where signs depicted Obama as Hitler as evidence of the dangerous environment.
The 76-year-old leader of the Chicago-based movement, which embraces black nationalism, predicts things will only get worse.
Farrakhan says Obama is in trouble, and that what he calls the "white right" is conspiring to make Obama a one-term president. Farrakhan says America needs to support Obama because he is the country's "last chance" to improve.
