In a tweet misspelling the chairman’s name, Trump, who nominated Powell to chair the central bank in 2017, questioned whether Powell is a greater enemy of America than Chinese President Xi Jinping.

President Donald Trump continued his attacks on Federal Reserve Chairman Jerome Powell on Friday, calling Powell an “enemy” as the Fed resists drastically altering monetary policy at the president’s whim.

Trump later deleted the tweet and replaced it with one correctly spelling Powell’s name.

The president’s invective seems to have been inspired by China’s announcement Friday that it will impose additional tariffs on $75 billion in U.S. goods, ramping up the ongoing trade war.

It’s also possible Trump was responding to statements Powell made during a meeting with bankers Friday morning. Although Powell reportedly said the Federal Reserve was prepared to cut interest rates if necessary, the chairman was noncommittal about when these cuts could come or how steep they would be.

After setting his sights on Powell, Trump posted a series of tweets in which he said the U.S. would be “better off” without China and “ordered” U.S. companies to find alternative business partners.
