During President Donald Trump's first 100 days of his second term, U.S. Immigration and Customs Enforcement (ICE) arrested over 66,000 illegal immigrants and deported more than 65,000, with significant focus on individuals posing threats to public safety and national security. A notable portion of these arrests involved gang members, including those from Tren de Aragua and MS-13, which are now recognized as foreign terrorist organizations. The enforcement efforts were bolstered by nearly 600 agreements under the 287(g) Program, allowing local authorities to enforce federal immigration laws, leading to substantial operations such as a recent joint action in Florida. Homeland Security Investigations (HSI) has also concentrated on workplace compliance, arresting over 1,000 illegal workers and imposing significant fines on businesses. These actions contributed to a drastic reduction in illegal crossings and encounters, with a reported 99% decrease in individuals evading capture and a sharp increase in arrests of suspected terrorists.

ICE reported that during Trump's initial 100 days in office, over 66,000 illegal immigrants were arrested and more than 65,000 were deported, focusing on those considered threats to public safety and national security.

Approximately 75% of those arrested were accused of committing crimes, with arrests including 2,288 gang members from groups like Tren de Aragua and MS-13, which are classified as foreign terrorist organizations.

The 287(g) Program facilitated close to 600 agreements with local law enforcement, significantly increasing immigration enforcement capabilities and resulting in large-scale operations, such as the arrest of nearly 800 individuals in Florida.

Homeland Security Investigations has been targeting illegal employment, arresting over 1,000 undocumented workers and levying fines exceeding $1 million against non-compliant businesses.

The number of illegal crossings and encounters has drastically decreased, with a reduction of 95% in encounters and a 99% drop in individuals avoiding capture, alongside a 655% rise in arrests of suspected terrorists.

A recent operation dismantled a human smuggling ring responsible for bringing between 500 to 700 unvetted migrants into the U.S. annually, underlining the ongoing focus on national security threats.

The Trump administration's measures have also included the construction of additional border barriers, contributing to decreased illegal migration levels reminiscent of those in the 1960s.
