John McCain, R-Arizona, will endorse former eBay executive Meg Whitman Friday for governor of California, a Whitman spokesman said.
Although Whitman hasn't officially announced her candidacy, McCain will endorse the Republican at a town hall meeting in Orange County and then join her in Fresno for a news conference. Whitman's spokesman Mitch Zak said that McCain's support "continues the campaign's momentum."
"John McCain is an American hero," Zak said of the 2008 Republican presidential nominee. "We're honored and humbled to have his endorsement. We're looking forward to working with him to improve California."
Whitman served as national co-chair of McCain's presidential campaign. She received another endorsement Thursday when House Minority Whip Eric Cantor, R-Virginia, announced that he was backing her.
"The state needs a leader with a creative vision, with a formula for success that can address the fiscal challenges that you face and there is no one better than Meg Whitman," Cantor said in a statement posted on Whitman's web site. "I'm very honored to be part of her team."
Republicans former Rep. Tom Campbell and California Insurance Commissioner Steve Poizner have officially announced their intentions to run for governor of California in 2010.
