It was actually the first time in 10 years that GDP was above the unemployment rate, a fact corrected at a White House briefing on Monday by Kevin Hassett, chairman of the White House Council of Economic Advisers (CEA).
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".
But the Obama administration also celebrated economic gains, with a 5.1 percent GDP in the second quarter of 2014 and four quarters of growth above the 4.0 percentage rate.
"The history of thought about how errors happen is not something I can engage in, because from the initial fact to what the president said, I don't know the whole chain of command", Hassett said.
On Monday morning, Trump tweeted that "The GDP Rate (4.2%) is higher than the Unemployment Rate (3.9%) for the first time in over 100 years!" "You'd have to talk to the president about where the number came from, but the correct number is 10 years".
On social media, the Fox News Research Twitter account posted an embarrassingly accurate pushback to one of Trump's lies.
After relaying an incident in which he had inadvertently given an incorrect figure to Sarah Huckabee Sanders, the White House press secretary, Hassett repeated that the president had made a mistake. "When President Obama left, after eight years in office, he had only created 195 000 jobs for African-Americans".
On Sunday, Trump said in a tweet that "the Stock Market is up nearly 50% since Election".
