The former president of the 95-year-old organization, who heads LULAC’S new political arm, said too much was at stake for Latinos under another Trump presidency.

The 95-year-old League of United Latin American Citizens has endorsed Vice President Kamala Harris and Minnesota Gov. Tim Walz, breaking with its past practice of not formally supporting any political candidates.

The historic endorsement of the Democratic presidential ticket is the first for the civil rights group, which formed in 1929 to protect the rights of Americans of Mexican descent. LULAC leaders announced the endorsement first to NBC News and plan to join Harris and Walz at a rally in Las Vegas on Saturday.

The endorsement was made through its political action committee, the LULAC Adelante PAC. LULAC is a nonprofit with a social welfare arm, and under federal tax law it cannot make political endorsements.
