David Trone, whose Maryland District 8 Democratic congressional primary campaign is off to a bit of a rocky start, has hired Andrew Friedson, Comptroller Peter Franchot’s longtime aide.

The campaign announced on its website Wednesday that Friedson, who managed Franchot’s 2010 reelection campaign, served as deputy chief of staff and is currently his communications director, will join Trone’s team as a senior advisor.

Trone, a major Democratic contributor and co-founder of Total Wine & More, has given generously to Franchot over the years. He and family members have contributed at least $22,000 since 2006, according to FollowThe, a database operated by the nonpartisan National Institute on Money in State Politics.
