"If you look at the collective body of evidence, the notion that what we're seeing right now is just a continuation of trends is not super defensible", Hassett said.
"I guess I have a magic wand", Trump said, pointing to 4.2 percent GDP growth in the last quarter.
But Trump still hadn't changed his false tweet as of Monday night. But as of 3.15 pm in NY, shortly after Hassett conceded the error and hours after the claim was challenged in news stories, Trump's false tweet about GDP and unemployment remained online.
On social media, the Fox News Research Twitter account posted an embarrassingly accurate pushback to one of Trump's lies.
World class narcissist and former President, Barack Obama, gave a speech on Friday at the University of Illinois Urbana-Champaign, where he brazenly laid the current state of political division within the country at the feet of President Donald Trump and the GOP. But Obama was actually talking about boosting manufacturing jobs, not economic growth.
Asked about the veracity of the statement later that day at a White House press briefing, Hassett said: "So I can tell you what is true. I'm sorry, and again, I'm not the chairman of the Council of Twitter Advisers".
"We numbers geeks here at the White House are grateful when the press finds mistakes that we make - we don't like making mistakes but we're grateful when they're pointed out because we want to correct them". Trump has been in office less than 20 months.
