A former Homeland Security official during President Donald Trump’s first administration, who authored an anonymous op-ed sharply critical of the president, is calling on independent government watchdogs to investigate after Trump ordered the department to look into his government service. Miles Taylor was once chief of staff at the Department of Homeland Security and warned in an interview with The Associated Press of the far-reaching implications of Trump’s April 9 memorandum. Trump’s policies have raised average U.S. tariff rates from around 2.5% when he returned to the White House to 15.4%, the highest since 1938, according to the OECD.
