Unfortunately, it isn’t the press Biden was mocking - it was the American people.
Critics of the Left who complain that the MSM is beholden to the Democrat Party may have it exactly backwards: The Democrat Party is made up of politicians hand-picked by the MSM - so who is beholden to who?
So, the reason why the MSM laughs at Biden holding no press conferences and taking only softball questions, is because Biden is behaving exactly according to script - their script.
Perhaps it’s both ways. The Bible talks about those who are deceived and being deceived.
