Harris has spoken by phone to the presidents of Guatemala and Mexico but has made few other public moves to reinforce the idea that she is focused on addressing the root causes of migration in Central America. Traveling to Connecticut shortly after her role was announced, Harris promoted the $1.9 trillion stimulus package and the childcare policies within it. She spent Easter weekend in southern California — but did not travel to the nearby U.S.-Mexico border. That trip involved a stop in Oakland, where she touted the White House’s infrastructure plan. During her Chicago visit, where she spoke about vaccines, Harris picked up a slice of cake at a local bakery — a detour that some conservatives, including Sen. Ted Cruz, attacked as a sign she hasn’t prioritized the border.
