🇺🇸美国检察官对杰伊 •鲍威尔展开了刑事调查，这涉及美联储总部价值25亿美元的翻修，大大升级了特朗普政府与中央银行的对峙。 US prosecutors have launched a criminal investigation into Jay Powell over a $2.5bn renovation of the Federal Reserve's headquarters, sharply escalating the Trump administration's confrontation with the central bank. Powell said on Sunday that the Fed on Friday received grand jury subpoenas and a threat of criminal indictment from the justice department relating to his testimony before Congress last summer about the renovation. He said the legal action was a pretext to rein in the Fed's independence to set interest rates.
