President-elect Donald Trump has named Kevin Hassett to head the National Economic Council, a role that puts him at the center of the administration’s policy discussions on everything from trade to taxes and deregulation.

The move brings Trump closer to completing his economic team, with U.S. trade representative taking the last remaining key position.

Trump made the announcement in a post on Truth Social.

Trump also appointed lawyer Jamieson Greer as U.S. Trade Representative on Tuesday.

For two years during Trump’s first term, Hassett served as chairman of the Council of Economic Advisers, where he supported Republican corporate tax cuts and defended Trump’s tariffs.

Hassett, 62, also worked with Trump’s son-in-law Jared Kushner on immigration and supported a move to end the lifting of sanctions on countries that buy Iranian oil.

The appointment came as Trump renewed his promise to increase tariffs on all Chinese goods imported into the United States by another 10% and impose 25% tariffs on all products from Mexico and Canada. Such a move would end a regional free trade agreement.

Trump is scheduled to be sworn in as the next US President on January 20th. He cited illegal immigration and illegal drug trafficking as reasons for the tariffs.

Hassett previously worked as a fiscal policy researcher at the conservative think tank American Enterprise Institute before Trump nominated him to the White House in 2017.

Late last week, Trump announced his intention to nominate Scott Bessent, founder of hedge fund Key Square Group and veteran market professional, as his Treasury secretary.
