President Donald Trump is considering suing Federal Reserve Chair Jerome Powell, White House press secretary Karoline Leavitt said Tuesday.

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.”

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.
