Ouch...this is pretty damning video for Trump. At the 0:16 mark, you hear a national union leader in January 2017 talk for 34 seconds about all the great promises Trump made to him for protecting unions. Then at the 1:23 mark, you see that same union leader in a 2 minute ad talk about how Trump failed to deliver on all of the promises made. And then he endorses Biden for President after that.
