Do you know when the invitation was made to Trump? It had to have been before yesterday.
Presidencia México. 16h @PresidenciaMX
En días pasados, el Pdte. @EPN invitó a ambos candidatos presidenciales de EUA a un diálogo sobre la relación bilateral entre México y EUA
In past days the President invited both candidates for US Pres to dialog on the shared relationship of the U S & MX
I found one news report that says the invitation was sent out last week. FWIW, the invitation was extended to both Crooked and Trump.
