This administration is so corrupt. The government should not target specific private institutions just to score political points. Grotesque abuse of power.

Important step from CMS to begin conducting risk adjustment data validation (RADV) audits for *all* MA contracts each year. If implemented well, this could, in effect, reduce MA risk scores by a few percentage points. But a few things to keep an eye on:

Two other closing notes. First, while reporting of invalid diagnoses is part of why risk scores are higher in MA, more intensive coding of *valid* diagnoses is more important. Addressing coding intensity differences attributable to valid diagnoses requires tools beyond audits.

The fake AI citations in the MAHA report are obviously embarrassing. But worse is what this says about how they are evaluating the real studies -- so much work in this space is just garbage correlation-not-causation. I cannot imagine they are thinking about evidence quality.

My very hot take: CBO is basically the most functional component of the legislative branch. The staff are super smart, non-partisan (their analysis annoys both Ds and Rs), and prolific--putting out incredibly helpful public materials and backup data. It's Congress's jewel.

95% of people who lost coverage when Arkansas instituted "work requirements" had jobs. You have to look at what policies *do*, not what they are *called*.

Violent crime is at historic lows in Baltimore and cities across the country under the leadership of mayors who have brought together partners from law enforcement, the legal system, and communities to reduce violence. The president could learn a lot about leadership from them.
