Secretary of State Marco Rubio joined El Salvador President Nayib Bukele in mocking a U.S. court's order to halt deportation of migrants to that Central American country, a court filing posted Monday claims.

The U.S. Secretary of State thanked El Salvadorian President Nayib Bukele for taking in more than 200 alleged gang members in its 40,000-inmate prison for the "low cost" of $6 million.

El Salvador is agreeing to accept from the United States about 300 alleged members of a Venezuelan gang for one year.
