Rep. Alexandria Ocasio-Cortez (D-N.Y.) on Thursday, Aug. 29, defended her right to block people on Twitter against “ongoing harassment.” When Fox News host Laura Ingraham corrected her grammar, Ocasio-Cortez called her a “neo-Nazi Fan favorite.”

The Knight First Amendment at Columbia University, a day before, sent the freshman congresswoman a letter, urging her to stop blocking those with opposing viewpoints, calling the practice “unconstitutional” as @AOC account is a “public forum.”

“You use the account as an extension of your office to share information about congressional hearings, to explant policy proposals, to advocate legislation, and to solicit public comment about issues relating to government,” the letter states. “Many of your tweets staking out position on issues such as immigration, the environment, and impeachment have made headline news.”

“The @AOC account is important to you as a legislator, to your constituents, and to others who seek to understand and influence your legislative decisions and priorities,” it continued.

In response, Ocasio-Cortez said, “I have 5.2 million followers. Less than 20 accounts are blocked for ongoing harassment. 0 are my constituents.”

“Harassment is not a viewpoint. Some accounts, like the Daily Caller, posted fake nude photos of me & abused my comments to spread it. No one is entitled to abuse,” she added.

Back in July, Ocasio-Cortez was sued by former New York Assemblyman Dov Hikind, a Democrat and New York GOP congressional hopeful Joseph Saladino after their accounts were blocked.

In reply to Ocasio-Cortez’s tweet, Laura Ingraham tweeted “‘Fewer’ than 20 account…,” jeering her grammar. The word “fewer” is correct when it used for countable nouns.

The New York lawmaker fired back, saying “See? You’re a neo-Nazi fan favorite and I don’t block you for defending white supremacist viewpoints and mocking gun violence survivors.”
