Washington DC - President-elect Donald Trump has nominated Ron Johnson to be US Ambassador to Mexico in his upcoming administration.

On Tuesday, Trump shared a post to his Truth Social platform, in which he explained that Johnson will be working closely with his Secretary of State nominee, Marco Rubio, to "promote our Nation's security and prosperity through strong America First Foreign Policies."

"Together, we will put an end to migrant crime, stop the illegal flow of Fentanyl and other dangerous drugs into our Country, and MAKE AMERICA SAFE AGAIN!" he added.

Johnson – who shares the same name as the current senator of Wisconsin – had previously served as the ambassador to El Salvador during Trump's first term.

He is also a former Green Beret who has more than 20 years of experience working for the Central Intelligence Agency.

His appointment comes as Trump has vowed to implement the largest deportation effort in US history on day one of his presidency and has threatened tariffs against Mexico, Canada, and China to put pressure on them to address the overflow of immigrants and drugs coming into the US.

According to Politico, officials in Mexico are relieved at the nomination of Johnson, as it had been rumored for weeks that Trump was going to instead tap Arizona senate candidate and MAGA loyalist Kari Lake to the role.
