I must be reading some tabloid rather than the WSJ: "In an effort to equalize the treatment of all unaccompanied minors, Mexican children potentially could be given more legal rights, the official said."

From The Wall Street Journal:

 

A senior administration official said Thursday the White House wants the ability to offer Central American children a "voluntary return" as soon as they are apprehended by Border Patrol, as Mexican children are now. That allows a migrant to return to his or her country without a formal deportation order. The White House also is seeking some sort of "expedited removal" for Central American children who don't have a "credible claim" that would allow them to stay under U.S. law.

In an effort to equalize the treatment of all unaccompanied minors, Mexican children potentially could be given more legal rights, the official said.
