Democratic presidential candidate Bernie Sanders is set to pick up one of his biggest endorsements yet Thursday from the powerful Communications Workers of America union, sources told NBC’s Andrea Mitchell.
The group represents some 700,000 workers nationally, making it by far the largest union to back Sanders yet. CWA’s endorsement, which will be announced at a press conference at 11:00 a.m. Thursday at the union’s headquarters in Washington, comes as Sanders has lost out on a string of major union endorsements to Democratic front-runner Hillary Clinton, whose campaign now claims the support of unions representing 12 million workers.
