The mass-nullification of contracts made by our government is illegal, has shattered our scientific research capacity, and will hobble trust in the ability of the American people to rely on their own government, permanently.

A federal appeals court has ruled the EPA “likely acted unlawfully” in canceling billions of dollars in Biden-era climate grants. The funding remains temporarily frozen while the Trump administration decides whether to appeal to the U.S. Supreme Court.

Today, 25 states led by Oregon (which also led state litigation against previous Trump tariffs) filed lawsuit challenging Trump's massive new Section 301 tariffs. This is 3rd case against Section 301 tariffs. See my discussion here for more: reason.com/volokh/2026/...

Out today: part 2 of my blog with Maurice Obstfeld on why so-called "optimal" tariffs are not optimal. Within, we discuss the latest research on tariff incidence, and what we've learned from the Trump tariffs so far...

Part 2: One of the biggest impediments to "optimal" tariffs improving national welfare is that it is US households & businesses who have borne most of the burden of Trump's tariffs in practice. Read here:

I didn't grow up learning to pay taxes in order to avoid jail. I grew up believing that I should pay taxes because it was right and because the law was justly applied and because America meant something to me. We understand that's over now.

FLAG: Trump gets to keep tax immunity for himself, his sons, and the Trump Organization under the new 'deal' struck by Todd Blanche. The new order also reaffirms that Trump won't have to pay any taxes he might have owed the IRS.

US tariffs are taxes on Americans. The pass-through rate of the President's tariff spike in 2025 was 92%. Ninety two percent of the tariffs are paid by American consumers as higher prices. By Conservative and Liberal consumers—who have been lied to about that harm. www.aeaweb.org/articles?id=...

The Incidence of Tariffs: Rates and Reality

(Summer 2026) - In 2025, statutory tariff rates on US imports rose to levels not seen in over one hundred years. What were the implications for prices? On the one hand, shipping lags, exemptions, and ...

The United States is losing one of its most precious assets: its onetime status as the top destination for global talent. Current politicians are poisoning that well. The cost, shared by Conservative and Liberal Americans, will be incalculable and permanent.

Immigration changes are driving foreign researchers to leave the U.S. — or not come to begin with

Labs are seeing fewer applications from international students and researchers, and some doctoral students are considering leaving early.

This scumbag just assaulted me in a store in the Washington DC area, to film it for “content”. If you see him call the police and let them know there are warrants for his arrest.

Bordeaux, France, has now recorded more days above 40°C in 2026 alone than during the entire 105-year period from 1920 (when observations began) to 2025. This is deeply shocking.

I wrote last year about the US Administration's plans to eviscerate Optional Practical Training, America's largest single source of global STEM talent: www.piie.com/blogs/realti... That came to pass. The White House is sharpening its tools to shatter OPT, and thus kneecap many US universities.

When I heard about this it was hard to believe, but now it's public. The US Administration is planning the full destruction of Optional Practical Training, the US's largest single source of global talent. I wrote about the effects of eviscerating OPT earlier this week: www.piie.com/blogs/realti...

The US Administration just cut the duration of student visas. Many have worried that visa extension backlogs will risk some students' graduation. At @piie.com I highlight a deeper problem. The rule gives political appointees discretion to do what they've promised: block most students from staying.

Stop this insanity. We have to live together in this country. Just “screwing the other side” is the policy of poison. It will come to harm all Conservatives and all Liberals because we will ultimately need each other. Many great Conservative leaders in the past had the wisdom to see that.

“Trump has rejected disaster aid for Democratic-run states at the highest rate in the 47-year history of the Federal Emergency Management Agency.” Right now people in blue states are basically paying federal taxes as if they’re colonized territories of red states. www.politico.com/news/2026/03...

Another month has gone by, and the US State Department continues to conceal our monthly visa issuance data, which went dark last fall. Someone in Washington really, really does not want accountability for the actions they are taking to dismantle our legal immigration system.

The Global Vaccine Alliance (GAVI) has saved over a million children from being killed by terrible diseases: www.aeaweb.org/articles?id=... Its value does not just lie in stopping bad stuff from "reaching U.S. borders". Working as humanity's partner, not enemy, has incalculable value to Americans.

News in global health: Sen. Susan Collins announces that GAVI, the vaccine alliance, will get hundreds of millions of dollars in funding after all. Trump officials last year said they would halt funding.

This afternoon. Yes, my city is STILL occupied by roving military fireteams, for no reason whatsoever, on the personal orders of the president. Perversion of our troops, deploying them indefinitely against other Americans, is the opposite of Conservative.

Here's a larger data set. Note that the rank order is pretty good! The correlation coefficient is +0.934, where +1.0 is perfect. And a measure of getting the order right, which is called "rank correlation", is an amazing +0.980. tl;dr we're good at comparing, but we are the pits at quantifying

Outstanding insight into likely effects of student visa time limits on study and post-study training. Other countries will absorb some, but not all of the talent. The setback to scientific progress will concentrate in the US but will be global in scope and have lasting if not permanent effects.
