Muslim citizens of the United States face growing discrimination in daily life, manifesting itself in violence, vandalism and arson, a US congressional panel has been told.

Speakers on Tuesday said that evidence of anti-Muslim bigotry included inflammatory remarks made by elected public officials.

"We continue to solicit and receive the support of many Muslim Americans who love this nation and work with our government to protect it," Democratic senator Dick Durbin, chair of the Senate judiciary subcommittee chair, said.

"At the same time, many law-abiding Muslim Americans face discrimination and charges that they're not real Americans simply because of their religion."
