During a political trip to Connecticut on Friday, Maryland Gov. Martin O’Malley (D) worked in a fundraiser for an expected referendum on the same-sex marriage bill he signed into law this month.

Before the dinner, O’Malley attended a reception to raise money for Marylanders for Marriage Equality, the coalition leading the fight to uphold the state’s same-sex marriage law.

“I came up for the [dinner], and Governor Malloy kindly offered to pull together some friends ... because we will likely have a referendum on the issue of marriage equality,” O’Malley told reporters after his speech, according to an account in the Hartford Courant. “I don’t know what we raised. I hope we raised a lot.”

Opponents of the bill have launched a petition drive that, if successful, would put the legislation on hold pending the results of a statewide referendum in November.

O’Malley also appeared Friday on MSNBC’s “Morning Joe” as part of the same trip north.

The governor was back in Annapolis on Saturday, where he watched part of the proceedings on the floor of the House of Delegates from a nearly empty House gallery. Delegates were in session to debate dozens of bills they are trying to pass by a Monday deadline to send legislation to the Senate.
