Trump's top economic adviser 'leaving shortly,' president writes on Twitter Kevin Hassett, the president said, will be replaced by someone "very talented."

Top White House economist Kevin Hassett "will be leaving shortly," President Donald Trump wrote on Twitter on Sunday night.

"His very talented replacement will be named as soon as I get back to the U.S.," Trump wrote. "I want to thank Kevin for all he has done."

Hassett had served as chairman of the Council of Economic Advisers since being confirmed by the Senate in September 2017.

Prior to that role, Hassett was an economist at the American Enterprise Institute, which he joined in 1997. Previously, he was a professor at Columbia University's business school.

Hassett made waves last fall when he directly contradicted a tweet by Trump related to Gross Domestic Product and unemployment rates.

"I'm not," Hassett said at the time, "the chairman of the Council of Twitter Advisers."
