Mexican authorities on Thursday accused U.S. officials of violating their own rules in the cases of a so-called "Dreamer" and a mother of four who were recently deported to Mexico.
"In the frame of respect to U.S. law, the Chancellery highlights that the cases of Mrs. [Maribel] Trujillo and Mr. [Juan Manuel] Montes Bojorquez represent a violation to the express rules of deportation in that country," read a statement released by the Secretariat of Foreign Relations, also known as the Chancellery.
"Neither of the compatriots represented a risk to the security of North American society and neither of them has a criminal background," the statement continued.
DACA recipients, or Dreamers, are protected from deportation unless they commit a crime or leave the country without prior authorization from United States Citizenship and Immigration Services.
CBP claims Montes had left the country without authorization before being arrested, a charge his lawyers deny.
Montes's case has received attention from both sides of the political aisle, with Democrats and some Republicans such as Sen.

But some lawmakers celebrated the move.
Rep. Steve King (R-Iowa) posted a celebratory tweet with a beer that read, "First non-valedictorian DREAMer deported. Border Patrol, this one's for you."
Trujillo is an Ohio mother of four with no criminal record who was deported by Immigration and Customs Enforcement Wednesday.
"The compatriot is the support of her family and since 2002 has worked and contributed to her community in the United States," read the Mexican Foreign Relations statement.

"I'm disappointed that the case could not have been resolved in a manner that keeps this family together," said Portman.
Trujillo chose to leave her U.S.-citizen children in Ohio, and her request to reopen her asylum case is pending.
Mexican authorities pledged to continue consular and legal support for its citizens in the United States, and to strengthen dialogue with their U.S. counterparts "with the end of enforcing the Rule of Law."
Mexico's consular network in the United States is the world's biggest, with 50 consulates scattered around the country.
The network was bolstered with a 1 billion peso (about $50 million) allocation this year, as President Enrique Peña Nieto expanded the consulates' migrant protection powers.
