Maryland First Lady Katie O'Malley has apologized for calling opponents of a gay marriage bill “cowards,” The Washington Post reported.

O'Malley made her remarks Thursday at the annual Creating Change conference sponsored by the National Gay & Lesbian Task Force.

Speaking to a crowd at the Baltimore Hilton, O'Malley said of last year's effort to pass marriage equality in the state, “We didn't expect the things that happened in the House of Delegates to occur, but sadly they did, and there were some cowards that prevented it from passing.”

In a statement released the following day, O'Malley, a district court judge, said that she “let my feelings get the better of me.”

“I deeply respect that there are strongly held and differing views on marriage equality in Maryland but hope that our state's elected officials will come together to fairly address this important issue for our families and children,” she said.

Democratic Delegate Jay Walker, who voted last year against the bill, called O'Malley's remark “borderline insulting.”

“Call me a coward, but I'm going to stand by my faith and my principles, as well as on my constituents' beliefs. Forget politics, my mom and dad did not raise a coward. … When you start name calling, you cross the line of respect,” Walker said.
