You are totally making things up. I’m not even worth $1 million. Nor even $500k. I don’t even own a house! I am one of the lowest net worth members of Congress, trade no stock, and take no outside income. My filings are public. I loathe corruption, and your lying is disgusting.

The reality: whenever I allow public comments I receive a flood of antisemitism, swastikas, things I don’t even want to mention. I’m not happy about shutting off comments, but that’s X. Tell Elon: he broke it, he can fix it. Meanwhile it’s the only way I can remain on Twitter.

I'm not a "believer" in vaccines It's not a religion or faith or cult. I support vaccines because there is overwhelming evidence that vaccines have saved millions upon millions of lives. That's it.

So the Tories who hollowed out our armed forces over 14 years are furious that Labour hasn’t rebuilt them fast enough and refuse to accept any responsibility whatsoever for the state of affairs. Have I got that right?

27% of those (mostly children) infected in the West Texas measles epidemic so far have been hospitalized. In the infographic from my PLOS Global Public Health article last month I estimated about 20% typically require hospitalization

A historic, shameful moment in US history as it votes with Belarus, Russia at the UN. The gamekeeper has become the poacher. Churchill & Roosevelt turn in their graves.

Last week, the new owners of the Observer wrote to tell me they would *not* be issuing me with a new contract. So...I want to say publicly that it was an absolute privilege to speak on behalf of my Observer colleagues during our strike. I don't regret doing so. And I learned so

Is there ANYTHING that Trump has done in the last 40 days - inside the US, or with Canada + Germany to Ukraine - that is not EXACTLY what Putin wanted? Could the Russian intelligence services have ever dreamt of a more perfect candidate and policies to serve Russia’s interests?

Sometimes vaccine efficacy is subtle Sometimes it isn't

Word of the day is ‘ingordigiousness’ (19th century): extreme greed at the expense of principles.

Make a huge mistake. Then make a false claim about how you fixed it. They did it for PEPFAR. Now Ebola. I follow this particular topic VERY closely, so here's what really happened and why this isn't true AT ALL...🧵

Many thanks ⁦Wolf Blitzer⁩ for hosting me ⁦The Situation Room⁩ on a very large and dangerous measles epidemic in West Texas with our first reported measles death in an unvaccinated school-aged child, an awful tragedy. But we’re still early…

What more proof do you need that vaccines work

SNL does the Zelensky - Trump meeting. Hilarious.

Trumpism is alive and well in Britain. Several major UK politicians backed the president in some quite shocking ways – and must now be held accountable. Here are 7 of them:

You start a trade war. Then cry ‘foul’ when the country you’ve targeted retaliates (which is what happens in a trade war). And then you promise hell, fire and brimstone cos you’re not getting your way 🤷🏻‍♂️
