Joe Biden has picked up another endorsement from a top Nevada politician, with Lt. Gov. Kate Marshall announcing that she will back the former vice president’s White House bid. Marshall joins two of the state’s four U.S. House members, Reps. Dina Titus and Steven Horsford, in backing Biden. Marshall plans to campaign with Biden on today in Reno. Biden has spent the weekend campaigning alongside Titus and Horsford in and around Las Vegas ahead of Saturday’s caucuses.
