President Joe Biden has joined picketing United Auto Workers in Michigan on the 12th day of their strike against major carmakers. It's a demonstration of support for organized labor unparalleled in presidential history. He told workers Tuesday to “stick with it." He exchanged fist bumps with grinning workers a day before former President Donald Trump makes his own visit to meet with UAW members. Biden has repeatedly sided with the UAW during the strike. Strikers chanted “no deals, no wheels” and “no pay, no parts” as Biden arrived at the General Motors distribution center west of Detroit.
