DETROIT: The powerful United Auto Workers union on Wednesday endorsed Hillary Clinton’s White House bid and questioned Donald Trump’s support of its members. In a statement, UAW President Dennis Williams lauded the Democratic frontrunner as someone who “understands the complexities of multinational economies and supports American workers. In 2009 she fought for preserving collective bargaining rights and stood up against attacks on collective bargaining when we needed her. She’s an advocate for expanding overtime rules to include more working families, she believes in equal pay, paid family leave, and quality, affordable child care.” The union’s backing will be important in battleground states in the industrial “Rust Belt,” such as Wisconsin, Michigan, Ohio and Pennsylvania, which are thought to hold the keys to November’s election. Clinton said she was honored by the endorsement.
