President Donald Trump said Wednesday that Federal Reserve Chair Jerome Powell has kept interest rates too high and that he might call the central bank chief.

(Reuters) - President Donald Trump on Monday kept up his verbal assault on Federal Reserve Chair Jerome Powell over the Fed's refusal for now to further cut interest rates, rattling financial markets growing ever more fearful that Trump may ultimately try to fire the U.S. central bank chief over the matter.

The president said he has “no intention” of ousting Jerome H. Powell, the Fed chair, but the administration’s willingness to challenge norms regarding the central bank’s political independence is causing concern.
