These are the White House staffers working with Kamala Harris on curbing Central American migration Brittany Shepherd WASHINGTON — Vice President Kamala Harris has begun to assemble a team to assist her in efforts to stem the migration surge from several Central American countries into the U.S., which has created one of the Biden administration’s first major challenges. President Biden last month assigned Harris to take on this issue, similar to the role he played on migration in the Obama administration. Harris’s task, according to a member of her team, is to lead diplomatic efforts to “engage Mexico and the Northern Triangle to address the root causes of migration and to oversee the flow and use of U.S. aid,” as opposed to more granular immigration-focused issues surrounding the U.S.-Mexico border.
