LULAC, nation's oldest and largest Latino civil rights organization, to endorse Kamala Harris for president

The nation's oldest and largest Latino civil rights organization, the League of United Latin American Citizens (LULAC), will do something it has not done since its founding in 1929 — it will endorse a presidential candidate, CBS News has learned. 

The organization's political arm, the LULAC Adelante PAC, will endorse Vice President Kamala Harris on Friday. 

The endorsement comes with Harris set to hold rallies in Glendale, Arizona on Friday and Las Vegas, Nevada on Saturday. They are two critical battleground states with large Latino populations.
