President Claudia Sheinbaum expressed her disagreement with the “unilateral deportations” of Mexican nationals living in the U.S. and Trump's “Remain in Mexico” policy.

The Trump administration is ending use of a border app called CBP One that has allowed nearly 1 million people to legally enter the United States with eligibility to work.
