Congress had Clapper testifying before a committee. Clapper was saying that yes the Russians did mess with the 2016 election. But he wasn't very convincing to me. Every thing he said was a generality, and opinion or a conclusion. He never spoke of real evidence, not even a wiretapped phone call or intercepted email or snail mail. No statements like, "We followed Russian embassy staffer so-and-so-ski to a face to face meeting with [any heavy weight person] on such and such a date and time. We eavesdropped the meeting and heard them discussing [payments, jobs, embarrassing emails, protection from prosecution, locations of dead drops, other spy stuff]". No cancelled checks, no deposits of large amounts of cash. Clapper never said anything solid, that could be checked, he just bloviated.
Clapper did manage to get several hours of TV time on Fox.
