Community activists and civil rights groups are urging the mayor of Los Angeles to revoke a permit allowing a white supremacist group to hold a weekend demonstration at City Hall.
Coalition spokeswoman Danielle Heck said Wednesday that the groups shouldn't be allowed to gather because they practice hate speech and seek to incite violence.
She says she expects thousands of counter-protesters to oppose the National Socialist Movement's event on Saturday.
National Socialist Movement regional director Jeffrey Russell Hall says the First Amendment gives his group the right to gather.
A spokeswoman for the mayor referred questions to the police department.
Police Sgt. Lisa Turvey says the permit allowing some 150 white supremacists to gather was granted in March.
