Commentary: Kamala Harris’ border mission should be a Mexico mission too

The Biden administration should avoid the Trump-era mistake of reducing the entirety of the U.S.-Mexico relationship to the single issue of immigration. The administration has made Vice President Kamala Harris its point person at the southern border, and she has been engaging with Mexico and Central American nations to embrace a regional approach to migration, which is laudable. But starting with her May 7 meeting with Mexican President Andrés Manuel López Obrador, announced over the weekend, the vice president should broaden the scope of her Mexico agenda to cover the complex array of economic, environmental, security, energy and rule-of-law issues that define U.S.-Mexico dealings.
