Statement from Michael and Susan Pretti
Parents of Alex Jeffrey Pretti

“We are heartbroken but also very angry.

Alex was a kindhearted soul who cared deeply for his family and friends and also the American veterans whom he cared for as an ICU nurse at the Minneapolis VA hospital. Alex wanted to make a difference in this world. Unfortunately, he will not be with us to see his impact.

I do not throw around the ‘hero’ term lightly. However, his last thought and act was to protect a woman. The sickening lies told about our son by the administration are reprehensible and disgusting. Alex is clearly not holding a gun when attacked by Trump’s murdering and cowardly ICE thugs. He had his phone in his right hand and his empty left hand is raised above his head while trying to protect the woman ICE just pushed down, all while being pepper sprayed. 

Please get the truth out about our son. He was a good man. Thank you.

Health Insurers Are Denying More Drug Claims, Data Shows

Research on insurer coverage rules is in today’s NY Times.

Denials are rising. Good managed care or bad administrative burden? Hard to know.

My kids know an American flag when they see one – but they don't yet know all that it represents.

When they're old enough, here is what I'm going to tell them:

SNAP work requirements have biggest effect on those least able to work Most people pushed out of SNAP in Connecticut didn’t find their way back in, even when work requirements were later reversed.

Ok folks, we know work requirements reduce benefits without increasing work (cc: @chloeneast.bsky.social)

But who loses benefits and what happens if work requirements are reversed?

SNAP Work Requirements Reversal and Program Enrollment This cohort study assesses the association of implementation and reversal of Supplemental Nutritional Assistance Program (SNAP) work requirements with SNAP enrollment.

RESULT 4:

Some towns reversed work requirements, what happened?

For our cohort, this was *not* associated with a change in SNAP enrollment — people didn't get back on the program

Implication: WR may be a "one-way door" out of safety net coverage

From a new JAMA HF pape that dropped last Friday

RESULT 3: Work requirements led to substantial coverage losses even for those with incomes

Translation — More evidence that not only about whether folks are working, even those with incomes are screened out...

This appears to be about paperwork.

RESULT 2: Sickest folks hit hardest by work requirements

Disenrollment risk was

≈2× higher for people with diabetes

and

≈5.5× higher for older adults (40-49) with ≥3 chronic conditions

Concerning evidence the sickest and most vulnerable folks are screened out by work requirements.

RESULT 1: Work requirements --> coverage losses

When CT imposed WR, SNAP coverage fell 25% + Medicaid enrollment was flat.

Translation — People lost nutrition support, not because they earned more, but because of paperwork.

If they were earning more they would be losing Medicaid eligibility.

New research letter led by Hannah Factor, a star PhD student here in Harvard's health policy program, finds that damage from SNAP work requirements is hard to undo, likely because of the administrative burdens involved with re-enrollment

Eric Roberts and @joefigs.bsky.social led a groundbreaking new study on Medicaid and Medicare, out today in NEJM. I’m lucky to have been a part of it.

Medicare saves lives. But is it enough to save lives of the most vulnerable Americans? The study suggests no; Medicaid still matters. (1/11)
