David Axelrod, former Obama adviser, Tuesday endorsed Don Beyer, one of seven candidates for Congress running in the June 10 Democratic primary for Virginia’s 8th district.

Axelrod is one of a series of former Obama aides who have lined up behind Beyer, Obama’s former ambassador to Switzerland and Liechtenstein, in the seven-person race to replace outgoing Rep. James Moran (D).

In the two minute video, Axelrod said he’s known Beyer since 2007 when both were campaigning in Iowa for Obama. He calls him “a great ally of the president,” praising his work heading the Obama administration’s transition team for the U.S. Commerce Department, his record as Virginia’s lieutenant governor in the 1990s and “treating his workers with dignity and respect” at his auto dealerships.

The campaign is throwing an Obama alumni happy hour Thursday at Arlington’s Café Asia, where former Obama Chief of Staff Pete Rouse, former Obama domestic policy adviser Melody Barnes, Obama’s 2012 campaign manager Jim Messina, and Julianna Smoot, the former White House social secretary and 2012 deputy campaign manager, are expected to attend.

The 8th congressional district covers Alexandria, Falls Church, Arlington County and parts of Fairfax County.

At least two more voter forums are planned before the election, both at the National Rural Electric Cooperative Association auditorium, 4301 Wilson Blvd in Arlington — the Progressive Democrats of America forum Wednesday, 7 to 9 p.m. and the Arlington Democrats forum, May 30 from 7 to 9 p.m. Beyer will not be attending the Progressive Democrats event.
