Minnesota made history last November when it became the first US state to defeat an anti-gay marriage measure at the ballot box.
But is there enough support in the state to legalize same-sex marriage?
State Senator Scott Dibble wants to find out.
Dibble says he has plans to introduce a bill to legalize gay marriage in Minnesota this week, according to the CBS affiliate in St. Paul.
'It’s just simply an amendment that removes the restriction that disallows some couples from getting married,' Dibble says. 'My strong sense, even from folks in greater Minnesota, is that they’re comfortable with this, they know that Minnesota has changed a lot and is continuing to change at a very rapid pace.'
Governor Mark Dayton has said he will sign a bill legalizing same-sex marriage if it passes both houses of the state legislature.
On the day that Minnesota defeated the anti-marriage measure last November, three other US states - Washington, Maine and Maryland made history when they approved gay marriage measures.
There are currently nine US states plus the District of Columbia that allow gay marriage. Illinois could become the 10th if its House of Representatives approves a bill passed by its Senate last week.
