A federal prosecutor in Virginia whose monthslong mortgage fraud investigation into New York Attorney General Letitia James has not resulted in criminal charges resigned Friday under pressure from the Trump administration. Justice Department spokespeople declined to comment. Trump administration officials have been aggressively pursuing allegations against James arising from alleged paperwork discrepancies on her Brooklyn townhouse and a Virginia home. The Justice Department “has firm policies against using investigations and against using prosecutorial power for achieving political ends,” Lowell wrote. But the Trump administration has repeatedly disregarded norms and traditions meant to protect Justice Department prosecutors from White House political influence.
