one of the reasons they're so mad at "no kings" is that they thought they were going to get a different kind of protest. they *want* the black bloc to be out there fighting with the cops. those are the images they've been trying to generate from "go." instead--

MAGA Rage at “No Kings” Boils Over—and It Quickly Backfires on Trump

We're spending $20B to bail out Argentina, but they cut USAID down to the bone, causing deaths around the world. The entire budget of USAID, the whole agency, was $21B last year. Shameful.
The Trump administration confirmed that the U.S. bailed out Argentina.
Treasury Secretary Scott Bessent said he had directly bought Argentine pesos in global currency markets in a bid to relieve pressure on the nation’s embattled President Javier Milei, a supporter of President Trump.
