Immigration and Customs Enforcement has arrested nearly 33,000 migrants in the United States since President Donald Trump returned to the White House, nearly outpacing the number of interior arrests in the last fiscal year under former President Joe Biden, according to senior Homeland Security officials.

ICE — the enforcement arm at the Department of Homeland Security — has been under immense pressure to ramp up arrests of undocumented immigrants in the United States, resulting in tense calls with the White House and infighting among officials. But in doing so, they’re also grappling with “maxed out” detention space, according to a senior ICE official.

“We are maxed out. We’re at 47,600,” the senior ICE official said, adding that the agency is looking to grow its detention space. ICE detention space is at roughly 120%, according to internal data shared with CNN.

In Trump’s first 50 days, from January 20 to March 10, ICE made 32,809 arrests, according to agency officials. The breakdown of those arrests includes:

14,111 were convicted criminals

9,980 had pending criminal charges

8,718 had other immigration violations

Some of those arrested have been released at the direction of judges or over medical or humanitarian concerns, though it’s unclear how many. Officials told reporters that those decisions are made at the senior level.

In fiscal year 2024, ICE conducted 33,243 at-large arrests, meaning that they were done in the community. Agency officials didn’t share how many of the arrests made in the last 50 days were at-large arrests. They also didn’t share deportation numbers.
