On September 25, Joe Biden made history as the first sitting president to walk a picket line when he joined striking members of the United Auto Workers (UAW) in Van Buren Township, Michigan.
Standing with UAW President Shawn Fain, Biden told the strikers through a bullhorn, "You deserve the significant raise you need and other benefits." But a big raise for the UAW could very well come at the expense of one of Biden's core campaign promises.
