As Maryland's gay marriage debate moved from the Senate, which approved the bill, to the House, Delegate Don H. Dwyer Jr. claimed lawmakers who support the institution are lying under oath.

Dwyer is leading the GOP effort to derail the measure in the House.

The Ann Arundel County Republican kicked up lots of dust last year when he attempted to impeach Attorney General Douglas F. Gansler for directing state agencies to recognize the out-of-state legal marriages of gay and lesbian couples.

Dwyer has announced he's taking another stab at the effort this year with a measure that would end the recognition. But first he's joined with the National Organization for Marriage (NOM), the nation's most vociferous opponent of gay marriage, to block the gay marriage bill in the House.

“Homosexuality will be taught at some level to children attending public schools as has been ordered by the court in various states,” Dwyer said during a morning press conference on Friday.

The Maryland Republican Party has begun blanketing parts of the state with robocalls, which tell voters that Democrats are working to “destroy traditional marriage.”

“They are eroding the values [this] country and state were founded on by redefining marriage,” a female says in the message.

At a Friday hearing on the bill, Dwyer claimed that lawmakers in favor of gay marriage were committing perjury, because they know it's a lie.

“Today we find ourselves facing a decision that deep in our heart and our conscience we know is wrong,” Dwyer told lawmakers. “That 12 of you on this committee have sponsored a bill to redefine and destroy forever the God ordained institution of marriage.”

He added that lawmakers were about to ignore God's law on homosexuality.

“We all took an oath on opening day of this session, yet there are many here who do not understand that an oath is an appeal to God by him who makes it. That what he has said or shall say is the truth. It is the most solemn form under which one can assert or pronounce anything. To utter a falsehood while under oath is perjury, a crime of the darkest hue, one which God himself has declared that he will punish, and one which has made infamous and punishable by fine and imprisonment by the laws of the land.” (The video is embedded in the right panel of this page.)
