Fox had to literally stop calling itself a new agency. Fox does the same thing you claim MSNBC, CNN etc do. Just skewed to your own bias so you don't protest.
I am not sure when CBS ever became left wing. They have always been just right of center my whole life.
No, they don't. Yes, they are biased right, but CNN\MSNBC\ABC\NBC\CBS are nothing more than a direct mouthpiece for Democrats. Fox covered news stories that were negative for Trump. CNN/MSNBC actively colluded with the Dem to smear Trump and Republicans, and the majority of the stories are rumors at best, outright lies at worst. The leaked DNC emails proved that.
And CBS right of center? lol. Yeah, Dan Rather was the original fake dossier leftist hack with all his lies about George W and his service in the Air National Guard. Claimed his documents bashing Bush's record had been authenticated, which was a lie. Tried to swing the election in 2004 with his lies. Same playbook with the Russian dossier from Hillary and the DNC, which every leftist news organization promoted as truth, with none of it verified.
Fox, on the other hand, told everyone about Hunter Biden laptop and said it was authenticated, and now we know they were right. Meanwhile, MSNBC/CNN/ABC/NBC and yes, your "right of center" CBS STILL completely ignore it. Those same folks ran with the unverified dossier nonstop.
