(CNN) - President Bush will officially endorse John McCain's presidential run Wednesday at the White House. The two men will have a private lunch followed by a joint public statement.
The move by the president, who remained neutral throughout the Republican primary process, comes after a victory in Texas that gave McCain more than the 1,191 delegates required to claim the GOP nomination. The Arizona senator's remaining primary season rival, Mike Huckabee, withdrew from the presidential race Tuesday night.

UPDATE: CNN's Robert Yoon and Dana Bash report that McCain will pay a visit to Republican National Committee headquarters after his White House visit.
