Harris will receive an endorsement from the United Latin American Citizens organization.

The nation's oldest and largest Latino civil rights organization in the United States, the League of United Latin American Citizens, will do something it has not done since its founding in 1929 — it will endorse a presidential candidate, according to CBS News. The organization's political arm, the LULAC Adelante PAC, will endorse Vice President Kamala Harris today.

Harris will hold rallies in Glendale, Arizona, and Las Vegas, Nevada this weekend. They are two critical battleground states with large Latino populations.
