Gov. Bob McDonnell will headline a fundraiser Friday in Seattle for Washington Attorney General Rob McKenna, who is running for governor next year.

McDonnell, vice chairman of the Republican Governors Association, added the event to his schedule after McKenna ended months of speculation Wednesday and announced his goal to be the first Republican governor elected in Washington state in three decades.

McDonnell left Virginia on Wednesday for Chicago for RGA business.

He attended a reception at a White Sox-Mariners game for Chicago-based corporate donors who contributed more than $100,000 Wednesday night, according to Phil Cox, RGA’s executive director.  

 He will attend a lunch Thursday for donors who contributed more than $25,000 at the Chicago Club. The lunch will be hosted by Fred Malek, a major Republican donor who serves as chairman of McDonnell’s government reform commission.

McDonnell returns to Richmond on Saturday.
