So in the U.S., the security system here functions in a way that allows TSA, the Transportation Security Administration, to share data with other federal security agencies.

And traditionally, that's been used for tracking people who may be on government watch lists or no-fly lists that restrict them being able to fly within the U.S.

But what we're seeing under President Trump is that this information sharing was increasingly used or used for the first time

for immigration enforcement.

And in our reporting, we got a sense of the scale, which had not been previously known, which showed that there had been 31,000 records shared between TSA and ICE of passengers who had been flying during Trump's presidency who may have been potentially subjected to immigration enforcement.

They involved an Irish couple that had been in the U.S.

for more than two decades and were detained last summer by immigration authorities as they were trying to travel from Florida where they were on vacation back to New York.

And those parents were actually deported to Ireland

were forced to leave their children in the U.S.

in the custody of older siblings who were here.

There were also several high-profile cases of people being detained, including a college student who was traveling from Boston to Texas to visit her family for Thanksgiving last year.

There have been some intermittent cases that have risen to the public eye, but this is the first time that we've gotten an actual sense of the scope and realized that it's hundreds of people that have been arrested during Trump's presidency.

I spoke with Becky Ringstrom, who is a housekeeper and a mother living in suburban Minneapolis, who said she was following ICE officers.

She said agents streamed out of their cars and surrounded her, including one that she said was hitting her windshield as if he was going to break it with a tool.

After this, she was detained by the officers there, and she was charged with a federal crime, which is related to either assaulting or what's called impeding federal operations.

There have been other tactics that we've seen where people who are opposed to ICE say that they're following what they believe to be ICE vehicles, and then they realize that the vehicle leads them back to their own houses, showing that the officer knows where they live and who they are.

And another way was that people would say they would just see officers or unmarked vehicles that appeared to be federal officers parked outside of their homes or outside of where they work.

The Trump administration generally says that its officers are under siege and said that these were people who they believe either assaulted officers or were impeding and interfering with the operations that were at hand.

Tren de Aragua is a Venezuelan gang, a prison gang, and the name translates to train from Aragua, which is a state in Venezuela. And within Venezuela and within the region, they have a reputation, a notorious reputation for extortion and kidnappings and even contract killings. We've seen them increasingly talked about in the U.S., particularly in the political context.
