An observation about the investigations

Supporters of Trump seem to assume that because the congressional investigations don't have evidence of something that the same must be true of the FBI. What I observe is that the FBI does not seem to turn over information to congress as soon as the get it, to protect their own investigation. The FBI has been investigating the Russian meddling since last July, Congress since late January. The congressional investigations seem to be moving very slowly; they still haven't interrogated Mike Flynn. I would be surprised if the FBI has not interrogated Flynn.
