<div class="css-s99gbd StoryBodyCompanionColumn" data-testid="companionColumn-0"><div class="css-53u6y8"><p class="css-ac37hb evys1bk0">Prosecutors sent by Jeanine Pirro, the U.S. attorney for the District of Columbia, made a surprise visit on Tuesday to the Federal Reserve’s construction site, which is at the center of an investigation into the central bank, according to people familiar with the matter.</p><p class="css-ac37hb evys1bk0">The highly unusual decision to visit the Fed underscored Ms. Pirro’s intention to aggressively pursue her investigation into Jerome H. Powell, the Fed chair. Mr. Powell has been targeted by President Trump, who has blasted the chair for refusing to slash interest rates far below where they stand today.</p><p class="css-ac37hb evys1bk0">Mr. Trump’s push to investigate Mr. Powell, who has fiercely defended the Fed’s independence, appears to be colliding with the reality that the Pirro-led investigation imperils chances of quickly confirming a successor when Mr. Powell’s term ends on May 15.</p><p class="css-ac37hb evys1bk0">On Tuesday, the Senate Banking Committee announced it would hold a confirmation hearing next week for Kevin M. Warsh, Mr. Trump’s pick to replace Mr. Powell. The hearing will proceed despite the fact that a key Republican on the committee, Senator Thom Tillis of North Carolina, has said he will not advance Mr. Warsh unless the Justice Department drops the Powell investigation.</p></div><aside aria-label="companion column" class="css-ew4tgv"></aside></div><div data-testid="Dropzone-1"></div><div class="css-s99gbd StoryBodyCompanionColumn" data-testid="companionColumn-1"><div class="css-53u6y8"><p class="css-ac37hb evys1bk0">The confrontation at the Fed took place around 11 on a sunny Washington morning.
