The Trump administration has appointed a national security lawyer who entered the foreign service just four years ago as the top official overseeing the State Department's global workforce, according to three sources familiar with the matter and an internal email seen by Reuters. The hiring of Lew Olowski to run the department's Global Talent Management Bureau comes as President Donald Trump shrinks the federal workforce and looks to revamp the U.S. diplomatic corps to ensure a dedicated implementation of his "America First" policies. Olowski served as a senior counselor at the Department of Homeland Security under the first Trump administration.
