If the president could unilaterally change federal election law without Congress, it would destroy the design created by the Framers of the Constitution, says Cato’s @thomasberry.bsky.social.

The Pentagon's Retaliation Campaign Against Anthropic Is Unconstitutional The government punished Anthropic because the company refused to change what its AI model would say and do. That violates the First Amendment.

The @cato.org was proud to join @thefireorg.bsky.social, @progresschamber.org, @eff.org, and the First Amendment Lawyers Association to file a brief supporting Anthropic in its lawsuit against the Pentagon.

The government is punishing @anthropic.com because Anthropic refuses to change what its AI model will say and do. That retaliation campaign is unconstitutional, because the First Amendment protects the right to design AI models with limits and guardrails as its creators see fit.

If President Trump tries to take control of the midterm elections by executive order, he'll be defying the Constitution in an attempt to trample the authority of Congress and the states and the rights of voters. The time to draw a line is now, says @walterolson.bsky.social.

Draw the Line Now Against a Trump Election Takeover Everyone who cares about federalism and the Constitution, especially lawmakers, should draw the line right now against the idea of letting Donald Trump seize control of elections.

And @walterolson.bsky.social urges the administration to drop this plan now rather than run into certain trouble in the courts:

Emergency Authorities and the Constitutional Allocation of Election Power Elections are always high-stakes, and public trust in election processes is important. But invoking vague emergency statutes to exert more control over elections would raise the stakesβ€”and reduce publ...

My colleague Brent Skorup digs into the "emergency" statutes that Trump might invoke to justify an executive order on the 2026 elections, and why none of them would justify a presidential overhaul of federal elections:

Today at @cato.org we're covering the dangers of this reported executive order on the 2026 election from all angles. @stephenricher.bsky.social lays out just how disruptive a change it would effect:

The Framers Gave the Power to Regulate Elections to Congress, Not the President A federal judge recently held that β€œour Constitution does not allow the President to impose unilateral changes to federal election procedures.” It really is as simple as that.

If the president could unilaterally change federal election law without Congress, it would destroy the Framers' design. That is why any legal claim of inherent presidential authority to regulate elections during a supposed "national security emergency" must be vigorously opposed.

27.02.2026 19:02 πŸ‘ 32 πŸ” 11 πŸ’¬ 1 πŸ“Œ 1

The Constitution explicitly assigns to "the Congress" the power to "make or alter" election regulations "by Law" (i.e., by statute). That explicit textual command leaves no room for any claim that the President has inherent authority to alter election law by executive order.

Typically each Supreme Court Justice only writes one majority opinion for the set of cases argued each month. Today the Court issued an opinion written by Justice Alito for one of the cases argued in November, which means he is probably not the author of the tariff case opinion.

Florida bans noncitizens from handling voter registration forms, despite a lack of evidence that noncitizens are any more likely to abuse that trust than citizens. @cato.org has filed a brief supporting a challenge to the law as a violation of equal protection.

Supreme Court justices appear likely to side with president in FTC firing case After hearing arguments Monday, the conservative justices on the Supreme Court seem poised to give the president the power to fire people at independent agencies like the FTC and Federal Reserve.

I spoke with NPR immediately after yesterday's argument in the case that will likely overrule Humphrey's Executor. In my view, the only suspense left is how the Court will write the opinion, not what the opinion will hold.

The attorney general appoints an acting U.S. attorney for 120 days, and then "if an appointment expires ... the district court ... may appoint a [U.S.] attorney to serve until the vacancy is filled." This holds that the AG cannot make another appointment once 120 days expires.

The vast majority of the argument was devoted to the question whether the statute authorizes tariffs *at all.* Less discussed was whether these particular tariffs are justified as necessary to "deal with" a genuine emergency, given that trade deficits have existed for 50 years.

One thing I've never seen before: during seriatim questions when only one justice is allowed to speak at a time, Sotomayor asked Kavanaugh to nod yes if he was planning to ask about an issue, so she wouldn't have to. He did, so she passed.

Scott Bessent, Howard Lutnick, and Jamieson Greer were sitting right behind me and kept poker faces throughout (I glanced back when Roberts pressed the SG on who pays for tariffs).
