The Mueller report cleared the President of the bogus charge of collusion with Russia. To that end, the President thoroughly cooperated, and permitted his aides to speak to the Mueller team.
It's over. What Dems howl is "obstruction" is only the President choosing to defend himself against the slander. And a witch hunt this has been.
That being said, I welcome Mueller's testimony before this Senate committee. If the public needs to "see the movie", let them see Mueller grilled in public by Republicans. It's the only way the mainstream media will show an alternative to the Dems' narrative of slander.
