Democratic representative from New York Alexandria Ocasio-Cortez has accused NBC News of posting a misleading tweet regarding her role at the Democratic National Convention on Tuesday, reported CNN.

During her speech, she seconded the nomination of Senator Bernie Sanders for president, who after ending his run in April endorsed Joe Biden, but was still in line for the formal delegates count that took place Tuesday. 

Following Cortez’s speech, NBC tweeted, “In one of the shortest speeches of the DNC, Rep. Ocasio-Cortez did not endorse Joe Biden.” 

However, NBC deleted the tweet later and tweeted a screenshot of the previous tweet saying, ” This tweet should have included more detail on the nominating process.We have deleted the tweet to prevent its further spread, but it can be seen here for the record.”

It added in another tweet, “Ocasio-Cortez was asked by the DNC to second Sanders’ nomination. The nomination is a procedural requirement of the convention. Ocasio-Cortez has previously endorsed Biden, & her speech was similar in length to other nominating speeches.”

Following the clarifications, Cortez tweeted, “You waited several hours to correct your obvious and blatantly misleading tweet. It sparked an enormous amount of hatred and vitriol, & now the misinfo you created is circulating on other networks. All to generate hate-clicks from a pre-recorded, routine procedural motion.”

According to CNN, after Sanders dropped out of the presidential run in April, a deal was negotiated between both Sander and Biden’s campaign which allowed Sanders to keep the delegates he had already acquired, therefore, enabling him to fill statewide delegate and standing convention committee slots he would have been eligible for as if he still had an active campaign. 

The convention rules require a roll call and nominations for every presidential candidate who has passed the required number of delegates. Since Sanders was an eligible candidate under this criteria, Cortez was asked to second his nomination in her minute long speech.

Cortez herself acknowledged the confusing convention rules and clarified her role in the convention later in a tweet congratulating Joe Biden for his campaign. She said, “I was asked to 2nd the nom for Sen. Sanders for roll call. I extend my deepest congratulations to @JoeBiden – let’s go win in November.”
