In a democracy based on freedom and the rule of law, we don’t jail public officials—or anyone—because of policy disagreements. We need everyone to repudiate this nonsense because a president cannot act as a prosecutor, judge, jury and dictator.

I guess we know who is behind the writing some of these posts now.

Screenshot of a tweet from OSINTdefender (@sentdefender) on X. The tweet claims to show a close-up of a note that Secretary of State Marco Rubio handed to President Donald Trump during a White House roundtable. The text of the note allegedly reads, ‘Very close. We need you to approve a Truth Social post soon, so you can announce deal first.’ Below the tweet, a blurry photo shows a piece of White House stationery with partially legible handwriting and the words ‘Very close’ visible at the top.

We found a troubling emergent behavior in LLM.
*When LLMs compete for social media likes, they start making things up When they compete for votes, they turn inflammatory/populist
When optimized for audiences, LLMs inadvertently become misaligned—we call this Moloch's Bargain

"Death rates have not rebounded quite as researchers expected in the years since. In addition to COVID, increased deaths from heart disease, diabetes, chronic liver disease/cirrhosis, along with drug overdoses contributed to excess mortality."

71.5% of ICE detainees have no criminal convictions, according to government data.

Don’t fall for Trump’s lies about targeting the “worst of the worst.”

As Trump's regime terrorizes communities to fill up detention centers, remember that some of his biggest donors are private prison corporations.

So at the time the admin bragged they were cartel drug runners, then they joked about killing fisherman, then it seems someone realized all of that proves it was simply murder, and now they're retroactively claiming it was an undeclared war.

Still just murder, still can't blow up civilian boats.

Spoke with @charliesavage.bsky.social about how the administration is trying to backfill a legal rationale for US strikes in the Caribbean.

Seems by "determining" there is an armed conflict—without any basis in fact or law—POTUS is giving himself a license to kill.

I'm not sure how to convey this message in a half-acceptable way.
But, if the objective were to send SARCOV2 into endemicity, then healthy kids have to be exposed to the virus, ideally earlier than later. This is not 'eugenism'; it is bog-standard infection disease epidemiology.

Trump will leave us with a fundamental lesson:

The fact the US lost over 1.2 million people to COVID-19, a larger population than some states, and some people still claim we did too much to try to save people’s lives.

Millions of people became disabled by COVID-19 and Long COVID and the numbers continue to rise.
