Everything that’s happened over the past six months has been a response to an imaginary crisis. There is no immigrant invasion. No trade crisis. No scientific or governance crisis. Just people completely high off their own supply trying to fundamentally reorder society. None of this had to happen.

If you accept that non-citizens have no right to due process, you are accepting that citizens have no right to due process. All the government has to do is claim that you are not a citizen; without due process you have no chance to prove the contrary.

AUSA Hagan Scotten, former clerk for John Roberts, really put some mustard on his resignation letter.
BY EMAIL
Re: United States v. Eric Adams, 24 Cr. 556 (DEH)
Mr. Bove,
I have received correspondence indicating that I refused your order to move to dismiss the indictment against Eric Adams without prejudice, subject to certain conditions, including the express possibility of reinstatement of the indictment. That is not exactly correct. The U.S.
Attorney, Danielle R. Sassoon, never asked me to file such a motion, and I therefore never had an opportunity to refuse. But I am entirely in agreement with her decision not to do so, for the reasons stated in her February 12, 2025 letter to the Attorney General.
In short, the first justification for the motion-that Damian Williams's role in the case somehow tainted a valid indictment supported by ample evidence, and pursued under four different U.S. attorneys is so weak as to be transparently pretextual. The second justification is worse.
No system of ordered liberty can allow the Government to use the carrot of dismissing charges, or the stick of threatening to bring them again, to induce an elected official to support its policy objectives.
There is a tradition in public service of resigning in a last-ditch effort to head off a serious mistake. Some will view the mistake you are committing here in the light of their generally negative views of the new Administration. I do not share those views. I can even understand how a Chief Executive whose background is in business and politics might see the contemplated dismissal-with-leverage as a good, if distasteful, deal. But any assistant U.S. attorney would know much i i red oril, in this ily. wing the perset arthro he Reside is ving to,
give him that advice, then I expect you will eventually find someone who is enough of a fool, or enough of a coward, to file your motion. But it was never going to be me.
Please consider this my resignation. It has been an honor to serve as a prosecutor in the
Southern District of New York.
Yours truly,
Hagan Scotten
Assistant United States Att…

The American Bar Association has just called upon every attorney, regardless of their political views, to join them & stand up for the rule of law & at minimum insist that our government "follow the law." Every lawyer has an ethical responsibility to do so. www.americanbar.org/news/abanews...
We call upon our elected representatives to stand with us and to insist upon adherence to the rule of law and the legal processes and procedures that ensure orderly change. The administration cannot choose which law it will follow or ignore. These are not partisan or political issues. These are rule of law and process issues. We cannot afford to remain silent. We must stand up for the values we hold dear. The ABA will do its part and act to protect the rule of law.

We urge every attorney to join us and insist that our government, a government of the people, follow the law. It is part of the oath we took when we became lawyers. Whatever your political party or your views, change must be made in the right way. Americans expect no less.

The mempool continues to be almost empty. The UTXO set peaked at 188M around Christmas and continues to trend down since. It has now fallen below 180M. Next block: 1.02 ṩ/vB+ #mempoolreport

Last night, the mempool shrunk to a depth of less than four blocks worth of unconfirmed transactions before it bounced back. It seems that we will soon see non-full blocks. #mempoolreport
Last night around 1 AM, there were only 3.58 MvB of transactions waiting for confirmation. This low point is followed by the mempool growing to over 20 MvB by 10 AM.

The mempool has come down from over 105 blocks worth of transactions in the 1–2 ṩ/vB band to less than 16 blocks. If you had been waiting for low feerates to consolidate a lot of DCA outputs or move your wallet to a more blockspace efficient output format, now’s a good time! #mempoolreport
The mempool visualization from mempool.space shows that the transaction data waiting for inclusion in the Bitcoin blockchain has been trending down towards the mempool clearing altogether since Christmas.
