The co-founder of a Washington opposition research firm that produced a dossier of salacious allegations involving President Donald Trump met for hours with congressional investigators Tuesday in a closed-door appearance that stretched into the evening.
"Mr. Simpson told Congress the truth and cleared the record on many matters of interest to congressional investigators", Levy said.
Simpson's firm, Fusion GPS, hired a British intelligence officer who produced a dossier containing allegations of ties between Trump and his associates and Russian Federation.
Simpson appeared privately Tuesday before the Senate Judiciary Committee, one of several investigating Russia's interference in the 2016 election and any possible collusion with Trump associates.
Simpson is the first of three major players in the ongoing Russian Federation probes to speak with judiciary staff. Donald Trump Jr. and former Trump campaign chairman Paul Manafort both cut deals to speak with committee staff in private as well, but their dates have not been scheduled yet.
Simpson runs Fusion GPS. Dianne Feinstein, the panel's top Democrat, have also sought interviews with Trump Jr. and Manafort, following news of their meeting with a Russian lawyer past year looking to repeal Russian sanctions. It's unclear to what extent the allegations in the dossier have been corroborated or verified by the FBI since the bureau has not publicly discussed it.
Glenn Simpson's private research firm Fusion GPS was initially paid about a million dollars by wealthy Republicans to do research on Trump, and Democrats later asked him to dig up dirt on the then-Republican presidential nominee.
Leaders of the Judiciary Committee said last month that they were negotiating private appearances for Donald Trump Jr., who has attracted scrutiny for accepting a June 2016 meeting with Russians at which he expected to receive damaging information about Hillary Clinton, and for Paul Manafort, the former Trump campaign chairman.
