Story highlights Trump tweeted about CNN's coverage of Utah voting machine problems

But he wrote "country" instead of "county"

Tapper: "It's the difference of an "r" but kind of an important one"

(CNN) When Donald Trump misquoted CNN in a tweet, Jake Tapper took him to task live on air.

Just out according to @CNN: "Utah officials report voting machine problems across entire country" — Donald J. Trump (@realDonaldTrump) November 8, 2016

After the Republican presidential candidate incorrectly tweeted that Utah officials were reporting voting machine problems across the "entire country," Tapper issued a fact-check.

No. Utah officials reported machine problems across one entire COUNTY, not the entire COUNTRY. https://t.co/6jWMw7qzvQ — Brian Stelter (@brianstelter) November 8, 2016

"In point of fact, CNN is not reporting that," Tapper said. "The problem is 'problems across the county.' A county, not the country, as Mr Trump tweeted. It's the difference of an 'r', but kind of an important one."
