Jim Hoffa accused the union’s current president, Sean O’Brien, of "a failure of leadership," saying he boosted Trump’s campaign with a non-endorsement.

For the first time in nearly three decades, the International Brotherhood of Teamsters won’t endorse a candidate in the presidential race — a blow to the Democratic Party, which has reliably received the union’s approval for years.
