(Reuters) - U.S. President Donald Trump's decision on Wednesday to oust Attorney General Jeff Sessions and replace him with a noted critic of Special Counsel Robert Mueller raised immediate fears among Democrats about the future of Mueller's investigation of Russian interference in the 2016 election.
Trump appointed Matthew Whitaker, formerly Sessions' chief of staff, as acting attorney general under the U.S. Vacancies Reform Act, which lays out general rules for temporarily filling vacant executive branch positions.
