Washington ? President Bush said Wednesday that a constitutional ban on gay marriage that has been proposed in the House might not be needed despite a Supreme Court decision that some conservatives think opens the door to legalizing same-sex marriages.

“I don’t know if it’s necessary yet,” Bush said. “Let’s let the lawyers look at the full ramifications of the recent Supreme Court hearing. What I do support is a notion that marriage is between a man and a woman.”

Bush’s words were aimed at calming members of the GOP’s right wing, who are upset about the Supreme Court decision, said Patrick Guerriero, director of the Log Cabin Republicans, a gay-advocacy group. “I think what you’re seeing is a momentary time-out from the radical right’s temper tantrum,” he said.

In striking down a Texas law that made homosexual sex a crime, the Supreme Court on June 26 overturned its earlier ruling that said states could punish homosexuals for having sex.

Conservative Justice Antonin Scalia fired off a blistering dissent of the ruling.

The “opinion dismantles the structure of constitutional law that has permitted a distinction to be made between heterosexual and homosexual unions, insofar as formal recognition in marriage is concerned,” Scalia wrote. The ruling specifically said that the court was not addressing that issue, but Scalia warned, “Do not believe it.”

The Supreme Court’s decision was a broad ruling addressing privacy, and gay rights groups are saying they will use it to push for more legal rights.

The president was asked about whether he supported a federal constitutional amendment that would define marriage as a union between a man and a woman during an impromptu news conference that followed his announcement of a new global AIDS ambassador.

Rep. Marilyn Musgrave, R-Colo., was the main sponsor of the proposal offered May 21 to amend the Constitution. It was referred on June 25 to the House Judiciary subcommittee on the Constitution.

To be added to the Constitution, the proposal must be approved by two-thirds of the House and the Senate and ratified by three-fourths of the states.
