President Zelenskyy made it clear during our call yesterday—Ukraine wants peace. Continued support from the United States is desperately needed to aid the brave Ukrainians fighting against Putin's bloodthirsty, murderous invasion. I joined @CNN to discuss.

Trump is carrying out a pressure campaign of coercion against Ukraine—in effect aiding Putin. I joined @NewsCentralCNN to discuss my letter calling for Trump to rescind his diesel deal & to urge continued support for Ukraine in its fight against Putin's invasion.
Health and care of older Americans as good or better than peer countries. Not true for younger cohorts. The power of Medicare and the safety net for American seniors. See commonwealthfund.org/publica…

The Trump Administration wants to repeal the Full Fare Rule—prioritizing airline profits over consumer transparency. I’m demanding that the DOT Secretary do right by consumers & avoid deceptive ticket advertising practices.

It’s real, not science fiction. OpenAI’s rogue bots threaten civil privacy, national security, & public safety. We need protections & safeguards—like my Artificial Intelligence Risk Evaluation Act—against AI’s perils.

Our immigration courts are in chaos—intentionally. My visit today confirmed real life impacts of cuts in judges & staff, lack of notice & due process, no criminal record & often no attorney, among failings. Deporting, not justice, is the goal.

My recent trip to Ukraine confirms that Congress must counter Trump’s “mush” by passing the Russia Sanctions bill,&pushing more air defense&Starlink support. The Witkoff/Kushner Moscow visit is a setback to showing strength&force—all Putin understands.washingtonpost.com/opinions/…

Trump’s sustained strategic campaign to suppress mail voting should be summarily dismissed by the Supreme Court. As the USPS whistleblower shows, this system is completely impractical & illegal. Immediate clarity is essential. apnews.com/article/trump-mai…

A welcome step—& the only legally responsible one. Now Trump should end his reckless new USPS mail-in ballot rule designed to prevent millions of Americans from voting.

Suppressing votes is the real purpose of surging baseless investigations into purported fraud in CT & other states. Cravenly malign intimidation—CT must stand strong. cnn.com/2026/08/31/politics/…

"Trump and RFK Jr. are perpetuating the misunderstanding that cases of autism have been increasing in the population at an alarming rate, whereas what has happened is that diagnoses of autism are increasing in people who, in the past, would have been diagnosed with other conditions or missed altogether. They are now using this misunderstanding to scare people about vaccines, asserting that the artifactual increase in autism rates constitutes evidence of an epidemic produced by the harmful effects of vaccines. The results of this scientific illiteracy could be catastrophic." Why Autism Rates Are Rising—It Isn't the Vaccines quillette.com/2026/08/27/int…

The evidence that vaccines don’t cause autism is overwhelming. Also there’s the absence of a plausible mechanism for a vaccine link given that autism begins in early fetal development through the action of >100 autism genes. The vaccine-autism link is entirely fabricated by individuals and groups with self-serving agendas. Here’s my latest paper from @BakerInstitute bakerinstitute.org/research/…
At a federal autism advisory committee meeting yesterday, committee members explicitly named vaccines as a cause of autism — despite years of scientific evidence debunking any link between the two.

President Zelenskyy rightly feels Ukraine is turning the tide against Russia’s bloody invasion—but continued U.S. support is crucial for the country’s success. I joined @Morning_Joe to discuss.

The #FDA is weighing a “competency-based approach” to evaluating AI-powered #medical devices, modeled on how doctors get credentialed. “You can’t regulate generative #AI the way you regulate pills and cardiac pacemakers,” said @DavidBlumenthal, a professor at the @HarvardChanSPH. geneticliteracyproject.org/2…

Young children & their families hideously victimized by Russian kidnapping & other atrocities are awesome in their resilience & grace. The world must match their courage.

A moving celebration in Kyiv for Ukraine's Independence Day—a reminder that freedom is never free, & we must redouble our efforts to support this brave embattled nation against Putin’s murderous invasion.
David Blumenthal retweeted
The people of Poland understand what's at stake in Ukraine. America must do what's necessary—including my Russia sanctions bill—to stop Putin’s murderous invasion.

More than 210 leading medical, health and patient advocacy groups oppose recent executive order on childhood vaccines

Trump is throwing down the gauntlet to both sides in the Senate—nominating an FDA head who demeans vaccines, denounces reproductive rights, & degrades science. nytimes.com/2026/08/18/healt…
