3:12 PM PT -- Colby Covington just beat Robbie Lawler's ass in the Octagon, and won via unanimous decision. When he finally got a chance to gloat on the mic ... he shouted out the Trumps -- which was met with overwhelming boos from the crowd. It appears to be one of the first signs of rejection the Trump boys were met with throughout the afternoon.
1:50 PM PT -- Colby Covington now has the full support of all the Trumps, including the President ... who just wished him good luck ahead of his fight with Robbie Lawler.
