Native American groups plan to gather on the steps of New York's City Hall to demand an apology from Mayor Mike Bloomberg for a comment he made they say was racially insensitive.
Bloomberg is a Democrat-turned-Republican-turned-independent. He toyed with the idea of running for president as an independent in 2008, and often criticizes both sides of the aisle for getting caught up in partisanship.
Bloomberg was asked Thursday whether he thought partisan rhetoric contributed to the tragedy.
He said that it appeared to be the work of a deranged gunman, and does not blame "Sarah Palin or any other individual.''
