There will be tension between the now president ellect and the Mexican government about the deportation of the "amigos" 🕵and the wall to build between US and Mex.
The Watchtower risk manager could have advised to sell the "investments" in Mexico.
(WTS and the Trump government members have good contact because the property transactions).
