Queens Rep. Alexandria Ocasio-Cortez offered a robust defense of political “purity tests” at a rally in Los Angeles on Saturday, and implored fans not to compromise their liberal bona fides.

“For anyone who accuses us for instituting purity tests — it’s called having values,” the freshman representative said at a Bernie Sanders rally. “It’s called giving a damn. It’s called having standards for your conduct to not be funded by billionaires but to be funded by the people.”

The line is a reference to a Democratic debate moment between South Bend Mayor Pete Buttigieg and Massachusetts Sen. Elizabeth Warren, in which the millennial mayor defended a pricey fundraiser in the wine cave of a California billionaire. Buttigieg said criticism of the event was an unfair “purity test.”

The Democratic-socialist firebrand then offered a broad attack against her new colleagues in Congress, accusing many of being in the pocket of big donors — she did not name names.

“I can tell you as a member of Congress when people say that there is no difference between being funded by a handful of wealthy people and being funded by small grassroots donations,” she said.

“Let me tell you something, I go into work all the time and I hear people say ‘what will my donors think’ I hear that phrase. I hear and I see that billionaires get members of Congress on speed dial and waitresses don’t.”

Before taking the stage, AOC also offered some pre-game makeup advice to her fans on Instagram.
