Immigration and Customs Enforcement agents are being authorized to forcefully enter homes without a judge’s warrant, according to an ICE memo obtained by the Associated Press, pushing the boundaries of government searches and civil rights as protests against President Donald Trump’s use of federal immigration agents in cities throughout the U.S. continue.

The memo authorizes federal immigration officials to forcefully enter residences based on a “narrow administrative warrant,” the Associated Press reported, noting advocates’ view that the approach “collides with Fourth Amendment protections and upends years of advice given to immigrant communities.”

The memo has not been widely shared within Immigration and Customs Enforcement but has been used to train new ICE agents, with hires and agents in training being told to follow the memo instead of written training materials that contradict it, according to a whistleblower disclosure cited by the Associated Press.

The Associated Press noted it remains unclear how widely the memo has been applied to ICE operations.

Amid increasing ICE operations and protests in Minnesota, multiple reports have detailed federal agents forcefully entering homes of U.S. citizens.
