NBC News published a tweet afterward that seemed to imply that Ocasio-Cortez snubbed Biden.
“In one of the shortest speeches of the DNC, Rep. Ocasio-Cortez did not endorse Joe Biden,” a tweet from the official NBC News Twitter account said.
NBC News later deleted the tweet and added a screenshot of it to an editor’s note tweeted hours later that said, “This tweet should have included more detail on the nominating process.”
Ocasio-Cortez acknowledged in a tweet on Tuesday night that convention rules can be confusing and elaborated on her role there.
“If you were confused, no worries! Convention rules require roll call & nominations for every candidate that passes the delegate threshold,” she tweeted. “I was asked to 2nd the nom for Sen. Sanders for roll call.” She also congratulated Biden for winning the nomination.
NBC News’ misleading tweet rankled Ocasio-Cortez, who retweeted the editor’s note and slammed the network for how it was handled.
“It sparked an enormous amount of hatred and vitriol, & now the misinfo you created is circulating on other networks,” she said. “All to generate hate-clicks from a pre-recorded, routine procedural motion.”
She also chided the network for the timing of the editor’s note, asking how they were going to “fix the incredible amount of damage and misinformation that you are now responsible for?”
“Because a 1:15am tweet to slip under the radar after blowing up a totally false and divisive narrative across networks isn’t it,” she said.
NBC News declined to comment beyond sharing the editor’s notes and clarifications to a blog post on the subject.
“The DNC shared the procedural purpose of my remarks to media WELL in advance. @NBC knew what was going to happen & that it was routine,” she tweeted. “How does a headline that malicious & misleading happen w/ that prior knowledge?”
Ocasio-Cortez did not respond to a request for comment.
