Vice President Kamala Harris met with Mexican President Andres Manuel Lopez Obrador in Mexico City on Tuesday to discuss immigration policy, as part of her first foreign trip since taking office in January. Harris’ Mexico visit comes after she visited Guatemala on Monday, where she told Central Americans that “help is on the way” if illegal migration to the United States is to be curbed.

Lopez Obrador told reporters at the National Palace in Mexico City:“We are very pleased to have her here and we will touch on [border security], but always addressing the fundamental root causes.” Harris tweeted before her meet with Lopez Obrador: “The United States and Mexico share history and family. Our economies are tied, and our security relies on one another. I am here in Mexico City to renew our nation’s important partnership with Mexico.”

President Joe Biden put Harris in charge of the migrant surge at the southern border. The number of migrants this year is already the most since 2006, according to preliminary Customs and Border Protection data.
