The chairman of the White House Council of Economic Advisers, Kevin Hassett, is leaving his position at the end of the month. Hassett has held the post since September 2017, making him one of the longest-serving prominent members of the Trump administration.

Hassett has stated he isn’t a fan of tariffs, so some are questioning whether Trump’s threat of tariffs on Mexican goods played a role in his departure. It’s something he denied today on CNBC.

The Wall Street Journal writes:

One potential successor to Mr. Hassett could be the CEA’s chief economist, Casey Mulligan, an economics professor at the University of Chicago. The two other members of the council are Tomas Philipson, a health economist from the University of Chicago, and Tyler Goodspeed, who has researched the history of money and banking.
