In this Feb. 14, 2013 file photo supporters of gay marriage call for Minnesota lawmakers to legalize gay marriage at the State Capitol in St. Paul, Minn.
ST. PAUL, Minn. - Minnesota is set to become the 12th U.S. state where gay couples can get married.
A final legislative vote Monday will let the weddings start on Aug. 1.
Democratic Gov. Mark Dayton has pledged to sign the bill, and scheduled a ceremony at 5 p.m. Tuesday on the front steps of the Capitol in St. Paul to do so.
Minnesota is now the first state in Midwest to legalize gay marriage by legislative vote, and the third nationwide in just 10 days, joining Rhode Island and Delaware. Thousands of gay marriage supporters thronging the Capitol erupted into deafening cheers after the Senate's 37-30 vote; the House passed it last week on a 75-59 vote.
Only one Republican senator voted for the bill. Three Democrats from rural districts voted against it.
