Transcript for FBI director fired as Russia investigation reaches critical juncture

Bottom line now, where does the FBI investigation into Russian meddling and any possible collusions with the trump campaign stand. What we learned here and how Vladimir Putin is reacting to all of this. Here's ABC's Brian Ross. Reporter: The Russians were having a good laugh today about the firing of the FBI director. President Vladimir Putin, in full hockey gear, with his press secretary next to him, he was more interested in getting out on the ice. We have nothing to do with that. Reporter: Now at a critical juncture after almost a year. Officials tell ABC news, a federal grand jury is already impanelled. Pthe white house today was asked about reports subpoenas have Was the white house aware at the time of this decision and announcement that grand jury subpoenas in the case of Michael Flynn had just gone out? No. Nor would we -- should we have been.
