After yesterday’s surrender, we’re launching the largest Democratic primary program that we’ve ever run.
We will not back any Senate primary candidate unless they call for Schumer to step down as Minority Leader.
If you’re as pissed as we are, join this campaign to rebuild the Democratic Party. 👇

Sickening behavior by this agent. The fact that Mayor Adams has rolled out the red carpet for ICE is a stain on our city.
I was back at 26 Federal Plaza today, where an ICE agent violently threw this bereft woman to the ground in front of her kids. She had not touched him. She did not pose any threat. She had to be taken to the hospital. (🎥: Elias Eliahu)

Be sure you take a moment today to remember Charlie Kirk for exactly who he was.
Charlie Kirk Sept 27 2024: "Just so we're clear, the Haitians that are in Huntsville that are raping your women and hunting you down at night - it's only gonna get worse - unless Donald Trump wins
There will be hundreds of thousands of Haitians brought into Alabama and they will become your masters"

It's bullshit that I agree with David Frum. Things shouldn't have sunk so low that we've reached our level of agreement! We should be in the realm where we disagree on every issue in the news!

I watched Kimmel's three most recent monologues, convinced I had missed the thing MAGA was outraged about. But it looks like this is it.
