Acosta would badger Trump. He was terrible. Clearly put in place by CNN to damage Trump in any way possible. It wasn't journalism. Acosta made no attempt to hide his personal distaste of Trump. He would routinely cut off the President even when a reasonable answer was being provided. Acosta should have been thrown out of the Press Corps.
Doocy is a good journalist. His questions are not personal but merely address flaws in Biden's policies. Psaki had to work hard to dodge them, because the flaws are legitimate concerns. Doocy would cut off Psaki when Psaki would avoid answering the question. This is what every journalist should do.
