Washington, D.C. ? Televangelist Pat Robertson, founder of the Christian Coalition, endorsed Republican presidential candidate Rudy Giuliani on Wednesday.

“It is my pleasure to announce my support for America’s Mayor, Rudy Giuliani, a proven leader who is not afraid of what lies ahead and who will cast a hopeful vision for all Americans,” Robertson said during a news conference with Giuliani in Washington.

The former New York mayor backs abortion rights and gay rights, positions that put him in conflict with conservative GOP orthodoxy, and has been trying to persuade evangelical conservatives like Robertson to overlook their differences on those issues.

Evangelicals have split in their support for the leading Republican candidates. Kansas Sen. Sam Brownback, a favorite of Christian conservatives who dropped out of the race last month, endorsed fellow Sen. John McCain of Arizona on Wednesday. Former Massachusetts Gov. Mitt Romney recently announced that Paul Weyrich and Bob Jones III were on board with his candidacy.
