Trump’s US ambassador to Mexico is stepping down, to be replaced by a former CEO of GM and AT&T

The US ambassador to Mexico, Roberta Jacobson, is to step down this spring – a move that could further hurt a rapidly deteriorating relationship strained by major negotiations on trade, the controversial border wall project and an upcoming presidential election in Mexico.
An experienced diplomat and Latin America expert who took up the post in 2016, Jacobson is the latest in a string of high-level officials in the State Department to part ways with the Trump administration.
In a letter to embassy staff Thursday, Jacobson did not focus on her personal reasons for resigning, effective in May. She described it as a “difficult decision” but said it was “the right time to move on to new challenges and adventures.”
The Trump administration is looking to name Edward Whitacre Jnr, a former chief executive of both GM and AT&T, as her replacement.
Whitacre has also worked in the past with Carlos Slim, Mexico’s richest man, according to US and Mexican officials familiar with the decision.
