A third infant in Kentucky has died of whooping cough this year.

Reminder: The best way to protect against whooping cough is to get vaccinated. Adults should get a Tdap booster every 10 years, so please check, you may be overdue!

How awful. This is outright health disinformation, lying to the American people. Not only is there massive evidence showing no link between vaccines & autism, there’s not even a plausible mechanism based on what we’ve learned about the genetics of autism, some environmental exposures in pregnancy

you could fact check this β€” there aren’t 30 million illegal immigrants and there is no evidence that the presence of an immigrant in say houston has any impact on housing in madison, wisconsin β€” or you could note straightforwardly that this is just nazi rhetoric

How about we shut down the government for this very popular and specific goal and then, hear me out, we hold out for like a month and a half and then, ok this part is important, after a watershed election where we ran the table, ONLY THEN, fold and don't get the one thing we said we wanted.

I love kids. I have two of them. They’re amazing. However, kids are the absolute least self aware, clumsiest little puffins on the planet.

Please don’t drive tonight unless you have to, and if you do drive, drive super slow and pay 100% attention at all times.

Happy Halloween! πŸŽƒ πŸ‘» πŸ’€

The Senate is still meeting and holding votes as normal despite the shutdown.

The House has not held a vote in a month and a half now solely because Mike Johnson wants to prevent the release of the Epstein Files.

They've killed our government to save their pedophiles.

Here's why Vanderbilt's response to the Trump higher ed 'compact' is not enough | Opinion With the deadline looming for colleges to sign Trump's "compact," Vanderbilt must resist, says one university professor.

"Vanderbilt is failing in its moral responsibility to push back against rising authoritarianism and political coercion."

My effort to convince Vanderbilt (and all universities) to take a stand for the rule of law, the Constitution, and our democracy.

With millions at risk of losing SNAP in the coming days, a reminder: hunger doesn't happen in isolation. When food assistance disappears, families use rent money to eat. Then come evictions and homelessness.

Housing, food, healthcareβ€”it's all connected. Cut one thread and the whole thing unravels.

There are reports that the *entire* office of special education at the US Dept of Education has been cut. These hardworking folks ensure kids with disabilities get equal access to a quality education.

America’s children deserve better than this.

Trump Administration Will Rehire Scores of Experts Fired in Error

Seeing a lot of celebration of this as a win.

But at NIH we have seen this exact play before.

It looks like it is the Vought strategy -and to stop the lawless firings we have to see the bigger picture.

I don’t know who needs to hear this but the CDC is being eviscerated right now. America is not going to have any kind of outbreak response capacity after tonight. Americans’ health data is no longer secure. Say goodbye to federal public health in any capacity. It’s a disaster. We won’t recover.

Trump is now calling for the arrest of elected representatives checking his power.

What else is left on the path to full-blown authoritarianism?
