The chairman of the U.S. House of Representatives' Judiciary Committee on Friday subpoenaed a U.S. research firm's founder to give a deposition on his hiring of a former British spy to compile a dossier on alleged links between Russia and U.S. President Donald Trump's associates.
Rep. Bob Goodlatte, a Republican from Virginia, announced the move on Twitter a day after receiving a letter in which lawyers for Glenn Simpson, the founder of Fusion GPS, said their client "will not agree to an interview" requested earlier in the week.
"As part of our joint investigation into decisions made by DOJ in 2016, today I subpoenaed Glenn Simpson to appear for a deposition," Goodlatte posted on Twitter.
