I agree that local police assaulting journalists is awful, they should be fired and prosecuted. And I'm aware that Trump made some dumb ass comments praising that shit, but it doesn't constitute a war on the press. You're talking about some isolated disparate instances perpetrated by unrelated local police departments during a summer of protests and riots. That isn't an act of the executive branch of the federal government. The US doesn't have a strong presidential system like say for example France. The us president has virtually 0 control over any individual police departments other than threatening to yank some drug war funding.

There do exist levers the executive branch could pull to attack the press, e.g. via the FCC or by having the DOJ prosecute sources. The Trump admin didn't do those things despite all of his bluster. He basically ended the policy of aggressively prosecuting leakers and spent all day engaging with the media. Sure he's a shit bag who did crimes, but the war on the press stuff is overblown.
