I didn’t bother to click on the link to the full article. But from the headline it would appear that AP considers Mexico to be overseas.
The AP note-takers aren’t keeping pace with their bosses in the Administration, who consider “Mexico” and “USA” as different names for the same country.
It may not be “overseas”, but it is definitely a very foreign country. Been there 6 months combined on 4 trips. Definitely foreign, and if you think we have problems, oy veh!!
