The former British spy who wrote the infamous "Trump dossier" reportedly told special counsel Robert Mueller's team that Russia intervened to dissuade President Donald Trump from nominating Mitt Romney as secretary of State. The New Yorker reported Monday that Christopher Steele spoke with the special counsel's investigators last September as part of Mueller's investigation into Russian interference with the 2016 election. The magazine cited unidentified sources. Mueller was appointed in May 2017 to probe Russia's potential links with the Trump campaign, as well as "any matters that arose or may arise directly from the investigation." On Feb. 16, the special counsel obtained indictments against 13 Russian operatives, accusing them of involvement in a long-term campaign of misinformation against the U.S. to help Trump and disparage his opponent, Hillary Clinton.
