Heard about that too.
Now they are using doctored video to make Acosta look bad. The whole thing looks like it was planned by Trump's propaganda secretary with the connivance of the president.
Seems like the sort of thing authoritarians with editing suites do.
So my guess - Putin is framing the next stage in the attack on US institutions. Via infowars. Years 3-4 will be the second stage of the war against the press and truth.
When they take over, summon them to the House for an explanation.
