Wow. So the Supreme Court's DACA decision cites me, albeit indirectly. https://t.co/AnZHuiTzO3

Trump makes shit up: "We have the greatest economy we've ever had. $19.2 trillion is being invested right now in the United States."

[David J. Bier @David_J_Bier]

Imagine calling Trump of all people an “authoritative source” for a number. The most numerically challenged person in the history of our government.

JUST IN: President Trump urges ICE to continue "THE TRAFFIC STOP" hours after DHS Sec. Mullin reportedly ordered them suspended in most cases

Interesting to note that Trump believes 25 million illegals entered during the Biden invasion - the highest estimate we've ever seen from an authoritative source

Stephen Miller is undefeated. Death stops will continue

Eyewitness to ICE fatal shooting:

“I heard agony,” said Mary Hayes, who saw a screaming woman on her knees, next to a young girl. “I heard a howl that came from your soul, that your whole life had just changed and it was never going to be the same.”

Homan just admitted ICE has been endangering the public, its targets, and its own officers by making record vehicle stops with no enforcement upside! He admits that they could be arresting people outside of their cars but haven't been, yet ICE plans to restart them again!

Prosecutor: “Either these agents are completely untrained, or intentionally putting themselves in situations where they can justify firing into cars”

It's chaos and death all the way down. It's time to suspend racial profiling nationwide.

BREAKING: A man running from an encounter with U.S. immigration agents in Florida is struck and killed by a tractor trailer, police say. https://t.co/k8G9uok2vA

This is the fourth incident since 2025 where a person running from ICE has been struck and killed by a passing vehicle.

She says: “it is important to remember that the work ICE does to protect our country goes far beyond immigration enforcement. ICE’s Homeland Security Investigations (HSI) is tasked with combating cartels, human smuggling, child exploitation, forced labor, and more.” It is even more important to remember that DHS has defunded all that stuff to focus on mass deportation

[Sen. Susan Collins @SenatorCollins]

I spoke with DHS Secretary Mullin last night and urged him to cease all non-urgent vehicle stops in the wake of yesterday’s deadly Biddeford shooting. I am encouraged that the Department has agreed to do so.

An impartial investigation into the shooting in Biddeford needs to proceed, as the details surrounding this tragedy are important. It is extremely unfortunate that the agent involved did not have a body-worn camera. In April, measures that I authored in the Homeland Security funding bill became law, including $20 million for expanded use of body-worn cameras, $2 million for de-escalation training, and a 17% increase in the independent Office of Inspector General’s budget to investigate matters such as this shooting. The Democratic government shutdown delayed enactment and implementation of these important safety measures.

While it is clear ICE needs to improve its performance, it is important to remember that the work ICE does to protect our country goes far beyond immigration enforcement. ICE’s Homeland Security Investigations (HSI) is tasked with combating cartels, human smuggling, child exploitation, forced labor, and more. Eliminating ICE would make our country less safe and endanger the lives and welfare of countless individuals.

[Aaron Reichlin-Melnick @ReichlinMelnick]

This feels like a trap somehow.

@Richerd1378272 Does not change their agency’s mission! There are bad people who want to sneak in

[David J. Bier @David_J_Bier]

Good reporting from CNN. Border Patrol agent was on scene. A reminder that Border Patrol is supposed to be guarding the border, not invading our neighborhoods.

[David J. Bier @David_J_Bier]

This is overdramatic. It is not true that most ICE arrests come from vehicle stops. The largest bulk of ICE arrests still comes from state and local transfers, and numerous vehicle arrests could more easily be before or after they are in the vehicle.

[Wid Lyman @Wid_Lyman]

A new announcement that ICE agents are being instructed to immediately cease most vehicle stops nationwide is causing massive unrest within the organization.

“If targeted traffic arrests are banned, ICE will effectively be ABOLISHED from within.

Vehicle stops cover the vast majority of apprehensions - easily over 90% of total arrests.

Difficult to comprehend conceding the nation to those who want us dead.”
