Trump had been invited to the big event by UFC president Dana White and had expected to attend. But the Secret Service is cautioning against it due to security concerns, according to the sources.

White told TMZ Sports on Thursday, days after the election, that Trump was hoping to attend.

"Donald originally told me that he would come to the fight if he won," White told the site.

"I don't think Donald really realized what his duties were going to be had he won. No pressure to come, but it wouldn't suck that he came."
