Biden tells auto worker 'you're full of sh*t' for gun accusation

The exchange took place on Tuesday (March 10) morning when Biden visited Detroit's first new auto assembly plant in decades, which is owned by Fiat Chrysler Automobiles NV.

Biden met with workers from the International Brotherhood of Electrical Workers (IBEW) labor union, which endorsed him in February.

Biden hopes to take a big step toward the Democratic presidential nomination on Tuesday when six states cast votes, while Bernie Sanders aims for an upset win in Michigan that would keep his White House hopes alive.

With 125 delegates, Michigan is the largest prize of the six states voting on Tuesday, when a total of 352 delegates to July's Democratic nominating convention will be up for grabs.
