On the heels of two major endorsements last week, additional big-name supporters are expected to step forward to support Democratic state Sen. Mark DeSaulnier’s campaign for California’s 10th District, his staff said Monday.

His spokeswoman Shara Perkins confirmed Monday that DeSaulnier is currently in Washington, D.C., participating in meetings related to his campaign and that notable endorsements are expected to be announced later this week.

DeSaulnier has already received perhaps the most coveted endorsement in the race- The current representative of California’s 10th District, Rep. Ellen O. Tauscher, endorsed DeSaulnier as her successor last week. Tauscher has been tapped to serve as undersecretary of State for arms control and international security.
