Trump lashes out at Fed after Warsh backs rate hike

Trump's post was the second time this week he'd taken aim at his own appointees. After the Supreme Court struck down his attempt to regulate how states issue mail ballots, Trump wrote of the three justices he appointed: "These are not the people I interviewed to serve on the United States Supreme Court, they are merely a shell of their original selves."

White House officials spent much of the week publicly pressuring the Fed to hold rates steady. One former White House official told Reuters the president's social media post about the Fed was a tame response in the context of that campaign.

"The president is making clear he disagrees with the policy without explicitly saying Warsh is personally to blame, giving him a nickname, or threatening retaliatory action against the Fed," said the person, who spoke on the condition of anonymity because they were not authorized to speak publicly. "Instead he’s redirecting his ire toward trading partners, which have little to do with the monetary policy decision."
