Standing next to Rudy Giuliani, Pat Robertson just said at a press conference at the National Press Club that he's endorsing Giuliani because terrorism was the overriding issue of the time and that he trusted Giuliani would appoint strict constructionist judges, which is ultimately the most important concern of social conservatives. He also cited Giuliani's proven leadership, both on September 11 and in turning around New York City as mayor. Rudy backer Ted Olson also delivered brief remarks at this morning's event. Giuliani said of Robertson that "his advice is invaluable." More to come.

UPDATE:

Here are some quotes from Robertson:

"To me, the overriding issue for the American people is the defense of our population from the blood lust of Islamic terrorists."

"I think [Giuliani] has articulated a philosophy that he really is for the life of the unborn," Robertson said, referring to Giuliani's pledge to increase adoptions and decrease abortions as he did in New York. "Beyond that, the most important thing to social conservatives is the selection of judges. As long as the Supreme Court has ruled as it has, there's very little a lone politician can do about it on the national or state level…"

"I don't think evangelicals have coalesced around one candidate," he said, in response to a question regarding Paul Weyrich's endorsement of Romney and Sam Brownback's endorsement of McCain.

"Rudy Giuliani took a city that was in decline and considered ungovernable and reduced its violent crime, revitalized its core, dramatically lowered its taxes, cut through a welter of bureaucratic regulations, and did so in the spirit of bipartisanship which is so urgently needed in Washington today."
