The elimination of USAID is a moral atrocity and all involved made a choice to enable, and then lie about, ending the lives of some of the most vulnerable people in the world.

MAE SOT, Thailand (AP) - Mohammed Taher clutched the lifeless body of his 2-year-old son and wept. Ever since his family's food rations stopped arriving at their internment camp in Myanmar in April, the father had watched helplessly as his once-vibrant baby boy weakened, suffering from diarrhea and begging for food.
On May 21, exactly two weeks after Taher's little boy died, U.S. Secretary of State Marco Rubio sat before Congress and declared: "No one has died" because of his government's decision to gut its foreign aid program. Rubio also insisted: "No children are dying on my watch."
That, Taher says, "is a lie."

Stephen Miller said the quiet part out loud. Trump has “plenary authority,” then suddenly went silent. Their plan wasn’t to be public yet. Clearly, someone hit the panic button in his earpiece.

It gets weirder: CNN uploaded the interview with the “plenary authority” comment edited out.

A bunch of these circular AI deals are treating GPUs like they're real estate or Treasury bonds or something, rather than rapidly depreciating equipment with a high risk of obsolescence well within 5 years due to energy inefficiency and rising electricity costs.

www.bloomberg.com/news/article...

XAI’s financing would be split between about $7.5 billion of equity and as much as $12.5 billion of debt in the SPV, the people said. The vehicle will be used to buy Nvidia processors, and Musk’s artificial intelligence startup would then rent the chips out for five years, allowing Wall Street financiers to recoup their investment. The unique deal structure, backed by the GPUs as opposed to the company, could provide a playbook for tech firms looking to decrease debt exposure.

👆With thanks to the staff trying to make OSC “Experiences” save face for Kinga Surma, it does not.

Ford and Surma and the OSC Board betrayed Ontario’s kids.

We had one of the great science museums of the world. It changed lives.

Now we don’t. It doesn’t.

Renew and reopen OSC in 2026.

5) # students per month at CFSGX vs. (10/23) OSC?

If a federal judge, appointed by Trump, can call him “simply untethered to facts,” our White House press corps can as well.

storage.courtlistener.com/recap/gov.us...

In sum, the President is certainly entitled "a great level of deference," Newsom II, 141
F.4th at 1048, in his determination that he "is unable with the regular forces to execute the laws
of the United States." 10 U.S.C. § 12406(3). But "a great level of deference" is not equivalent to
ignoring the facts on the ground. As the Ninth Circuit articulated, courts must "review the
President's determination to ensure that it reflects a colorable assessment of the facts and law
PAGE 22 - OPINION AND ORDER
Case 3:25-cv-01756-IM Document 56
Filed 10/04/25
Page 23 of 31
within a 'range of honest judgment.'" Id. at 1051 (quoting Sterling, 278 U.S. at 399). Here, this
Court concludes that the President did not have a "colorable basis" to invoke § 12406(3) to
federalize the National Guard because the situation on the ground belied an inability of federal
law enforcement officers to execute federal law. Id. at 1051-52. The President's determination
was simply untethered to the facts.
c. Whether there is a Rebellion or Danger of Rebellion
Defendants also aroue that the Sentember 28 2025 federalization order is authorized

"This country has a longstanding and foundational tradition of resistance to government overreach, especially in the form of military intrusion into civil affairs. ...

"This historical tradition boils down to a simple proposition: this is a nation of Constitutional law, not martial law."

Furthermore, this country has a longstanding and foundational tradition of resistance to government overreach, especially in the form of military intrusion into civil affairs. “That tradition has deep roots in our history and found early expression, for example, in . . . the constitutional provisions for civilian control of the military.” Laird v. Tatum, 408 U.S. 1, 15 (1972); see also James Madison, Address to the Constitutional Convention (1787), reprinted in 1 Records of the Federal Convention of 1787, at 465 (Max Farrand ed., 1911) (“A standing military force, with an overgrown Executive will not long be safe companions to liberty. The means of defence [against] foreign danger, have been always the instruments of tyranny at home.”). This historical tradition boils down to a simple proposition: this is a nation of Constitutional law, not martial law. Defendants have made a range of arguments that, if accepted, risk blurring the line between civil and military federal power—to the detriment of this nation.

A year ago today I paddled around the West Island at Ontario Place - all summer looking at the trees from the water.

Unknowingly this was the last evening they stood, as they were cut down that night.

On Sept. 30, 1958, Canadian children were treated to a new show.
It featured a giant who told them to "look up!...waaaaaay up!"
For the next 27 years, the show was a fixture on CBC and is beloved to this day.
This is the story of The Friendly Giant!
