Opponent of a proposed gay marriage ban in North Carolina will rally against the measure on Tuesday, a day after it cleared the House.

The measure, which would define marriage as a heterosexual union in the North Carolina Constitution, was placed on a fast-track in the House, where it was introduced in committee at 1:30PM and cleared the full House by 6PM.

The Senate is expected to take up the amendment on Tuesday. If approved, voters would have the final say during the May primary election, not during the November general election as previously discussed.

Opponents of the ban will gather on Halifax Mall, located across from the state's Legislative Building, where they will be joined by singer Chely Wright. The 40-year-old country music star is among a handful of celebrities openly married to a person of the same gender. Wright and Lauren Blitzer married in Connecticut last month.

On Monday night, about 100 opponents of the amendment held a candlelight vigil outside the Pitt County Courthouse. “We're equal, equal love, equal rights,” they chanted in the pouring rain.

“I definitely don't think that we need to be putting discrimination in our constitution,” Aaron Lucier told CBS affiliate WNCT.
