U.S. Senator Jim Webb (D-Va.) announced he’s endorsing Leslie Byrne for Congress in the 11th District Democratic Primary.

Byrne, who became the first woman elected to Congress in Virginia history when she won the seat in 1992, is in a tough race with Gerry Connolly, chair of the Fairfax Board of Supervisors, and Gulf War veteran Doug Denneny. Democrats are hoping to regain the seat occupied by Rep. Tom Davis since 1994. Davis announced he will not seek re-election this year. The Democratic primary election will be held June 10. “I am convinced Leslie Byrne is our best candidate,” Webb wrote. “She shares my values about economic fairness and the need to re-order our national security priorities, both in Iraq and throughout the world.” Webb is slated to appear at a fundraiser for Byrne on March 31.
