U.S. President Donald Trump offered a veiled threat on Tuesday of a "major" lawsuit aimed at Federal Reserve Chair Jerome Powell in Trump's ongoing dispute over renovations of the central bank.

President Donald Trump said he’s looking at a “major lawsuit” against Federal Reserve Chair Jerome Powell over the agency’s over-budget remodel of its Washington headquarters, which has become a prominent attack line for Trump and his allies against Powell.

In a post on his Truth Social social-media network, Trump again urged the Fed to lower interest rates, writing: “I am … considering allowing a major lawsuit against Powell to proceed because of the horrible, and grossly incompetent, job he has done in managing the construction of the Fed Buildings.”
