Trump also chided O'Rourke over a quote he gave to Vanity Fair at the outset of his campaign, in which he said, "Man, I'm just born to be in it." 

"Anybody who says they were born for this, they’re in trouble," Trump said.

The former El Paso congressman announced earlier Friday evening that it had become clear he did not have the means to keep his campaign afloat, an acknowledgement of the financial struggles he has faced in recent months.

O'Rourke was unable to muster the same enthusiasm he garnered during his Senate campaign last year.

O'Rourke sparked unease among Republicans and even some Democrats with his unapologetic views on gun control, declaring in a debate that "hell yes" he would take back assault rifles as part of a sweeping agenda to curb gun violence.
