From the article: He lied about having the “biggest electoral win” in decades.
On Thursday, President Trump held a 75-minute press conference. In addition to announcing that R. Alexander Acosta would be his new labor secretary nominee, Trump also bragged about his electoral college victory. "I guess it was the biggest electoral win since Ronald Reagan," he said. That statement is false. Former presidents Barack Obama, Bill Clinton, and George H. W. Bush all received more electoral college votes than Trump, who garnered 306 votes. For comparison, The Hill reported that Obama received 365 electoral votes in 2008 and 332 votes in 2012.
Did you notice the word "guess" in his statement? This statement is obviously much more egregious and damaging than telling the American people they would receive a $2500 annual health care premium reduction and that Benghazi was a spontaneous response to an internet video., not to mention " I did NOT have sexual relations with that woman".
That has the same amount of value as " Romney beat up a kid in high school 50 years ago" .
