“Why did idiot McCarthy ONLY release it to Fox News?”
Because he knew that his BFF Paul Ryan, and Trump-hating Murdochs, would quash it. (We haven’t seen any footage since Monday, have we?)
He could have published online for all to see — but he didn’t.
At first that was my sentiment too. But the more I think about it, the more McCarthy seems to be playing the long game. If all of the video was dumped to the public there would have been an immediate uproar, then forgotten within a week by whatever the next "news" is in the 24/7 news cycle. But by instead dishing it out a little at a time, it stays in the news longer, as it should.
This is the exact playbook the Dims have done a lot -- making an old news story seem to always stay in the headlines with a drip by drip "new information on" type "events".
