There are plenty of people who attest to Biden's sound thinking and abilities, but Trump will keep hammering away just because he can.

Today it seems one of his acolytes is trying to alarm the American public by hinting that something is happening that Biden should declassify. Top Republican warns of 'serious national security threat,' rankling White House
The president's adviser plans to brief congressional leaders.

Considering that earlier in the week Jake Sullivan set up a meeting with the top House and Senate ("gang of eight") security folks, it sounds like the GOP guy Mike Turner is telegraphing to Trump. Since Trump is given absolutely no security briefings because of his unreliability, Turner is handing Trump a complaint point - something along the lines of "they should share this stuff with the former president" or "if I was in the White House now I'd have fixed this and told you all about it already." Along those lines. If Turner told Trump without permission, he'd be in deep shit and he knows that Trump can't keep a secret, so if he heard something top secret, he's share it immediately on his Truth Social platform.

Yeah, Willis shot herself in the foot, even it if doesn't have any impact on the case. There's a reason they call it "stupid in love."
