It hasn't taken long for Donald Trump to rip into Beto O'Rourke.
The Democratic nominee announced in a Tweet on Friday that he is ending his presidential campaign.
Hours later the US President said O'Rourke "quit like a dog" and used a cuss word to describe his political opponent at a "Keep America Great" campaign rally at BancorpSouth Arena in Tupelo, Mississippi.
The former Texas congressman has been of one Trump's most vocal critics.
