MEXICO CITY — The United States will finally have an ambassador in Mexico after more than a year without one.

Attorney Christopher Landau was President Donald Trump’s nominee for the embassy in Mexico. He was ratified unanimously by the Senate last Thursday.

Landau was a law clerk for two U.S. Supreme Court Justices, and has no diplomatic experience. But he’s fluent in Spanish and lived in Latin America, since his father was ambassador in Paraguay, Chile and Venezuela.

The U.S. Embassy in Mexico hasn’t had a head since Roberta Jacobson stepped down in May last year.

Among the issues Landau will have to face in Mexico are trade, migration, and drug and weapon trafficking.

Mexico is currently the top trade partner to Arizona and the U.S.
