Yes! They can arrest them for this kind of behavior. Let it go through the process and even if they're found unchargeable, it would slow things down tremendously. Just keep arresting them.

The Pontiff makes clear that he looks to the Bishop of El Paso, Mark Seitz, for leadership among US bishops in dealing with Trump and his immigration policies. Seitz has clashed with Republican bishops over border policy issues for years. www.americamagazine.org/vatican-disp...

Pope Leo tells border bishop: The American church needs ‘to be united’ on migration

“You stand with me, and I stand with you,” Pope Leo told El Paso’s Bishop Mark Seitz, chairman of the U.S. bishops’ committee on migration, when he met him and a U.S. delegation in the Vatican today.

JB Pritzker and Gavin Newsom are doing something new and important: They understand Stephen Miller's theory of fascist power politics, and they've developed a theory on how to combat it. More Dems need to reckon with Miller's understanding of the moment.

New from me:

Inside Stephen Miller’s Secret Plan to Normalize Trump’s Dictator Rule

He wants to supercharge searing civil tensions to get low-information voters to embrace their inner authoritarian. Exactly two Democrats appear to fully grasp this.

Reuters photographer Jonathan Ernst noticed that Bondi flipped open a file during the Senate hearing and he zoomed in.

Inside were her crib notes for attacking the senators.

The GOP now practicing Cliff's Notes Fascism

In other words, under oath Bondi was purely a performance.

Feels increasingly like a slow motion coup—slow because if it were going faster, the media might report it as a coup. Instead we’re “bucking norms” and “overturning long-standing rules.”

Trump's Truth Social posts might doom his invasion of Chicago just like they did in Portland.

From a just-filed lawsuit.

storage.courtlistener.com/recap/gov.us...

4. In one example that received significant news coverage, on September 6, 2025,
Trump posted on social media an image of the Chicago skyline in flames, stating “Chicago about
to find out why it’s called the Department of WAR,” including a depiction of himself in the image
of the fictitious warmonger character Lt. Col. Kilgore from the 1979 film Apocalypse Now, titling
the post “Chipocalypse Now.”

I thought the Epstein files would not be a big deal until Trump decided he’d start a civil war rather than release them.
