President Donald Trump signed a memorandum Friday directing several federal agencies to begin militarizing a stretch of the U.S.-Mexico border, a move seen as the latest escalation of his administration’s immigration crackdown.

The memo directs the Interior Department to give the Defense Department jurisdiction over the Roosevelt Reservation, an area of federal land stretching across Arizona, California and New Mexico. As such, any migrant crossing into the U.S. would be technically trespassing on a military base, allowing active-duty troops to detain them there until U.S. Border Patrol agents arrive.

While the status of Native American reservations is not impacted by the memo, the move could put U.S. military members in direct contact with migrants — possibly violating the Posse Comitatus Act of 1878. This federal law generally prohibits military personnel from being used in domestic law enforcement. See Page 13

Here are more Trump administration headlines from Saturday:

Tariffs latest: Guidance posted by U.S. Customs and Border Protection shows that about 20 products will be exempted from the “reciprocal” tariffs Trump imposed against China and other nations. These products include smartphones, computers, routers and semiconductor chips. The move is seen as a win for technology giants like Apple, which has a widespread manufacturing presence in China — where many of the exempted products are made. See Nation & World Page 4

Daylight saving: Trump is urging Congress to “push hard for more Daylight at the end of a day” by ending the biannual practice of Daylight Saving Time. His statement came after a Senate panel held a hearing Thursday on the merits of changing clocks ahead or behind one hour. In 2022, the Senate unanimously approved a measure to make Daylight Saving Time permanent, but it did not advance.
