ICE makes over 3,500 arrests during Trump's 1st week back in office

• Under the Biden administration, the average number of arrests of noncitizens with criminal convictions or pending charges in the fiscal year that ended Sept. 30 was 310.7 per day, according to an ICE report.

By the numbers: ICE on Thursday reported 538 arrests, on Friday the number announced was 593, on Saturday it was 286, on Sunday it was 956 and on Monday it was 1,179.

The big picture: Trump moved to unleash sweeping limits on immigration and asylum soon after taking office last Monday, declaring a national emergency on the U.S.-Mexico border and signing a flurry of executive orders.

• In the Republican-controlled Congress, lawmakers are pushing tough immigration bills — with the House last week passing and sending to Trump's desk the Laken Riley Act, which would require the detention of undocumented immigrants arrested for some crimes.

Meanwhile, House Oversight and Government Reform Committee Chair James Comer (R-Ky.) announced Monday that sanctuary cities Boston, Denver, Chicago and New York City were under investigation for "their impact on public safety and federal immigration enforcement."
