Dropping the investigation into former national security adviser Mike Flynn wouldn’t have greatly hindered the FBI’s overall counterintelligence investigation into Russian meddling in U.S. elections, according to testimony from former FBI Director James Comey.

Comey’s answers on Thursday on that line of questioning could be important as some opponents of the White House have suggested the Trump team’s alleged collusion with the Russians was most likely to come from a subordinate who had numerous contacts with Russia, such as Flynn did.
