"Covfefe" became the No. 1 trend on Twitter across the U.S. early Wednesday morning after Trump sent out what appeared to be an unfinished tweet with a typo.

"Despite the constant negative press covfefe," Trump tweeted shortly after midnight.

Trump deleted the tweet just before 6 a.m.

Moments later, he asked: "Who can figure out the true meaning of 'covfefe' ??? Enjoy!"
