In more news from the campaign trail, the biggest labor federation in the United States, the AFL-CIO, says it is withholding an endorsement for an individual candidate, a move that’s being seen as a victory for Democratic presidential candidate Bernie Sanders. The AFL-CIO was expected to announce its endorsement next week, after a vote by the executive council at the annual winter meeting. But in an email, AFL-CIO President Richard Trumka said the executive council will not be voting at the meeting, saying: "I have concluded that there is broad consensus for the AFL-CIO to remain neutral in the presidential primaries for the time being." The AFL-CIO endorsement is by far the most significant labor endorsement for a presidential candidate. Former Secretary of State Hillary Clinton has won the majority of labor endorsements to date, although National Nurses United has come out endorsing Bernie Sanders.
