Immigrants? Migrants? How about calling ILLEGAL ALIENS what they really are, "Yahoo News"?
If someone in the process of committing a Felony receives aid from a person who knows they are committing a Felony but aids them nonetheless of their own volition, that person rendering aid in the commission of the Felony is an accessory to the crime. If several persons, with knowledge of the crime conspire to aid someone in the commission of the Felony, that is consipiracy to be accessories to the crime, a separate charge.
If you get arrested for the Felony crimes of Accessory or Conspiracy, well, tough titty.
If you aid someone in the commission of a felony and death results from that felony, then you, too, can be charged with murder, just like a getaway driver in a robbery where someone gets killed.
In America, it doesn't matter who you are nor what office you may hold, you are not above the law.
Whine on, Yahoo.
