Secretary of State Marco Rubio is walking back an almost-total 90-day freeze on U.S. foreign assistance, making an exception for life-saving humanitarian aid, according to a memo the Miami Herald obtained.

According to Konbit Neg Lakay, more than 3,000 Haitians have come to Rockland under the humanitarian parole program Joe Biden opened in 2023.
