Illegal entries are down under Trump, but he's cut legal immigration even more than illegal immigration. The cuts to immigrants, refugees, parolees, students, H-1B workers, and fiancés were 2.7 times as large as the cut in Border Patrol arrests and evasions. www.cato.org/blog/trump-c...

Fox calls Cato a "notoriously pro-immigration think tank," which is hilarious and great but also unfair, since being pro-immigrant is an indirect, ancillary consequence of our pro-liberty mission, not the mission itself. We're just libertarians.

American crowd cheers as DHS trespassers can't get their guys. Why is it so hard to find crowds of Americans cheering like this when hard-working immigrants get dragged away from their jobs, removing labor competition? It's almost like they don't believe in zero-sum economics.

"Sorry to you people at the Cato Institute or wherever. I don't owe you an explanation for this. I just prefer this. However impolitic Bo French's tweet is... they no longer care about moral and social pieties that prevented them from expressing a preference" for homogeneity

Mullin is lying. These were not identified as "high-risk" nations, and it was not "tougher vetting" that cut entries. The absolute number of denials is LOWER now than under Biden. They just aren't even processing applications, and you owe every American sponsor an answer.

I remember when conservatives used to call liberals "snowflakes" for demanding that we care about how people's words make them feel. What's the word for demanding that we care about how people's colors make conservatives feel?

Immigrants from majority-Muslim countries are more highly educated, work in higher-skilled occupations, and have reduced federal, state, and local deficits by $1.1 trillion over the last 30 years. cato.org/blog/legal-i...

Every month, the US government is forcibly separating more than 3,000 spouses and children from their US citizen spouse or parent. The way that they don't care about our rights is evident every day. cato.org/blog/legal-i...

Trump has cut legal immigration from majority-Muslim countries by 96% from 21,096 legal immigrants and refugees in Dec. 2024 to 808 in Feb. 2026. Far more severe than anything in his 1st term, falling disproportionately on spouses of US citizens and skilled immigrants... www.cato.org/blog/legal-i...

Did you know that DHS is authorized by Congress to intentionally defame private individuals all day, every day and it cannot be sued for defamation? Now that you know that, does it make you more or less likely to believe anything it says? (Oh, he didn't illegally enter)

The District Court stays 3 illegal and unconstitutional DHS policies targeting Hispanic Americans: 1) warrantless entry to private construction sites without warrants, 2) preemptive detention of employees without suspicion, and 3) guilty-until-proven innocent detention

Fox News interviewed me about the public charge rule. "That's going to result in arbitrary denials. It's not possible to do this type of assessment and not result in people who would be self-sufficient being denied status."

House Judiciary Republicans also didn't like this tweet and read it into the hearing record because they want Border Patrol to be loose in the interior, stopping American citizens without probable cause.

House Judiciary Committee Republicans decided to read this tweet into the hearing record yesterday, I guess, because they hate work or something.

"Subsidized immigration enforcement insurance? Is that something crazy California cooked up to help out ICE targets?" Nope! It's a new federal welfare program by ICE to cover criminal and civil liability for local cops who violate rights while helping ICE 🤯 www.insurancejournal.com/news/nationa...

I testified yesterday at a hearing, again about immigrants and crime. Nothing makes the Republicans more infuriated than pointing out that immigrants lower the crime rate.

ICE is booking into custody 41 times as many noncriminals as in December 2024, while releasing 50% more people with criminal convictions or charges. What could be a better illustration of their priorities than that?

Releases of immigrants convicted or charged with crimes were higher under both Trump administrations and lower under Biden. www.cato.org/blog/ice-rel...

David J. Bier @davidjbier.bsky.social · 27/08/2026
Under Trump, ICE has not stopped releasing immigrants from custody. It has cut releases of noncriminal immigrants, while actually releasing 50% more immigrants convicted of or charged with crimes than in December 2024. Trump's priorities are clear. www.cato.org/blog/ice-rel...

Immigrants receive about half as much disability income as the average US-born citizen, which means that disabled immigrants are receiving significantly less disability income than the US-born disabled population.

David J. Bier @davidjbier.bsky.social · 27/08/2026
This is not an age effect: Immigrants, legal and illegal, are less likely to be disabled at nearly every age than the US-born. Immigration lowers the US disability rate. www.cato.org/blog/immigra...

David J. Bier @davidjbier.bsky.social · 27/08/2026
Trump's new public charge rules focus on immigrants with disabilities. Our research finds that immigrants are 24% less likely to be disabled than US-born citizens; illegal immigrants are 64% less likely. ⬇️ www.cato.org/blog/immigra...

I don't know any Dems saying he shouldn't be deported after he serves his time, but MAGA would have happily deported the victim/victim's family back to Peru, including her 4-year-old daughter. Caring about the victims of immigrant crime requires more than demonizing immigrants.

ICE admitted in court that it did, in fact, track down this man at his hotel with his 7-year-old daughter and gave him a threatening letter because he sent ICE Director Todd Lyons this email.

The videos can't capture the scope of what's happening. ICE is out of control. ICE accosted a man on his way to a medical appointment, handcuffed him, and forced him back to his house. Agents conducted a warrantless invasion of his home, where his 3 minor US citizen kids lived

ICE agent testifies about how he targeted people: "They're not doing nothing bad. They're just hanging." Q: "Where?" ICE: "Street, store, gas station, anywhere..." Q: "What do they look like?" ICE: "Hispanic males." Can't go anywhere as a Hispanic man in ICE's America.

If there were many more illegal immigrants, then the threat to Americans' lives and liberties is far more pronounced. There is a better way: fix the legal immigration system that caused the problem to begin with

David J. Bier @davidjbier.bsky.social · 17/08/2026
If the Census is missing tens of millions of illegal immigrants, then the crime rate for illegal immigrants would be even lower than we think it is. Trump apparently believes illegal immigrants are AMAZING for crime rates.

David J. Bier @davidjbier.bsky.social · 17/08/2026
Trump is adding $180 billion to the cost of mass deportation when he inflates the number, which calls attention to the fact that mass deportation is absurdly expensive to begin with. More workers to deport: the worse the math gets! houstonchronicle.com/opinion/outl...

David J. Bier @davidjbier.bsky.social · 17/08/2026
The @houstonchronicle.com published my explanation for why it makes no sense for mass deportation proponents to exaggerate the number of illegal immigrants: it makes their policy idea even more catastrophic for the country. www.houstonchronicle.com/opinion/outl...

Can you read a sentence like "the parent is formally beyond the reach of American courts and police" and not think about Trump's eyes lighting up? If you're asking why Trump would want a foreigner in the USA who is exempt from US law, you haven't thought about this enough.

David J. Bier @davidjbier.bsky.social · 06/08/2026
This section explains what is meant by the fiction of extraterritoriality. In theory, Congress could make any noncitizen in the United States subject to the fiction of extraterritoriality by making them exempt from US laws, but it would never do that, so Trump's order is wrong.
1333
David J. Bier @davidjbier.bsky.social · 06/08/2026
The fiction of extraterritoriality means that they aren't subject to US law in some way. Once again, they aren't even trying to explain how there is a fiction of extraterritoriality for these groups. They are just asserting it, like the first order

David J. Bier @davidjbier.bsky.social · 06/08/2026
In yet another act of impeachable unconstitutional defiance of the law, Constitution, and courts, Trump issues another executive order limiting birthright citizenship. Even if more narrowly than before, this is a high crime. Remove him

Given DHS's documented history of pushing false accusations against people they arrest or kill, we should have no confidence in its self-serving statement exonerating the agent before any investigation was complete cato.org/blog/new-doc...
14313
David J. Bier @davidjbier.bsky.social · 06/08/2026
DHS policy is not to use deadly force to stop a fleeing suspect. In this case, the suspect's flight would have ended his violation of any U.S. law, yet repeatedly, we have seen DHS agents shooting fleeing suspects and then being exonerated by their superiors.

David J. Bier @davidjbier.bsky.social · 06/08/2026
