(RNN) - Marco Rubio teased Donald Trump in a Friday speech by making fun of Trump's spelling mistakes in tweets he wrote to insult the Florida senator after Thursday's.
They all referenced Rubio after the two had a heated exchange at Thursday night's Republican debate.
Rubio pointed out that Trump called him a "chocker" instead of a "choker."
He didn't stop there.
"Great 'honer,'" Rubio said. "I think he meant to say great 'honor,' I don't know how he got that wrong because the E and the O are nowhere each other on the keyboard.
"How does this guy, not one tweet but three tweets, spell words so badly?" Rubio wondered. "I only reached two conclusions. No. 1, that's how they spell these words at the Wharton School of Business, where he went. No. 2, just like Trump Tower, he must have hired a foreign worker to do his tweets."
Trump later resent the tweets with corrected spelling.
It's not the first time Trump, a manic tweeter, has been criticized for his spelling errors online.
Last June, in a tweet slamming one of his favorite targets, MSNBC host Lawrence O'Donnell, Trump misspelled the word "dumber." He spelled it "dummer."
