PITTSBURGH—At least 250 people gathered on a downtown Pittsburgh street closed for the occasion were cheering U.S. Supreme Court decisions on gay marriage.

City Councilman Bruce Kraus told the crowd Wednesday morning, "To my fellow gay, lesbian, transsexual and queer friends, welcome to full equality."

City police have issued a permit for Wednesday's rally on Liberty Avenue, during which a portion of the busy downtown artery was to remain closed from 9 a.m. to 12:30 p.m.

The Delta Foundation of Pittsburgh organized the rally, which was called "Riot or Rejoice."

The Supreme Court struck down part of the federal Defense of Marriage Act, which kept married same-sex-couples from receiving some legal benefits that heterosexual couples receive, while another decision left in place a trial court's decision that California's Proposition 8 banning gay marriage is unconstitutional.
