Gray heads to China while federal probe heats up

District Mayor Vincent Gray’s planned weeklong business trip to China to sell the city’s investment opportunities kicks off this week just as public attention to the federal probe into his election campaign is increasing.

The trade mission is Gray’s first overseas trip as mayor and has been planned for months. But it comes at a time when question about the federal investigation into his 2010 campaign are multiplying, now that two other high-profile elected officials have resigned as a result of separate investigations.
