Recent reports of immigration arrests at U.S. airports, some of them captured in videos that have gone viral, stem from increased collaboration between the Transportation Security Administration and Immigration and Customs Enforcement, ICE sources tell CBS News. Now, the two federal agencies are collaborating more broadly on civil immigration enforcement. In a statement to CBS News, the Department of Homeland Security hinted at the increased immigration enforcement at airports. "DHS reversed the horrendous Biden-era policy that allowed aliens in our country illegally to jet around our country," DHS added. This administration is working diligently to ensure that aliens in our country illegally can no longer fly unless it is out of our country to self-deport."
