NEW YORK (CBSNewYork/AP) — Donald Trump may want to invest in spell check.

The GOP front-runner took to Twitter Friday morning to unleash against rivals Marco Rubio and Ted Cruz who took him on during Thursday evening’s GOP debate.

But his tweets contained numerous typos, drawing a barrage of attention on social media.

“Lying Ted Cruz and leightweight chocker Marco Rubio teamed up last night in a last ditch effort to stop our great movement. They failed!” he wrote in one, misspelling both “lightweight” and “choker.”

He misspelled both words again in another tweet:

In yet another posting, he spelled “choker” both the right way and the wrong way.

“Lightweight Marco Rubio was working hard last night,” he said in another tweet. “The problem is, he is a choker, and once a choker, always a chocker! Mr. Meltdown.”

In a different tweet, Trump also misspelled the word “honor” when he bragged about his performance during the debate: “Wow, every poll said I won the debate last night. Great honer!”

Rubio mocked Trump’s spelling mistakes, reading them aloud during a campaign rally in Dallas.

“‘He is a chocker. And once a chocker, always a’ — a choker, I guess that’s what he meant to say,” Rubio said.

The tweets were later deleted and resent without the spelling errors.

Rubio began the day Friday waging a fresh verbal assault against Trump, repeatedly calling the billionaire businessman “a con artist” during a round of morning television interviews.

Rubio also questioned Trump’s business background, attacked his preparedness to lead the nation, and charged that Trump has been “sticking it to the little guy” for decades.

“A con artist is about to take over the Republican Party and the conservative movement, and we have to put a stop to it,” he told “CBS This Morning.

At the same time, Rubio allies prepared to spend millions on Trump attack ads in key states.

The multi-faceted takedown effort comes four days before Super Tuesday.
