Alexandria Ocasio-Cortez’s Twitter lesson for House Democrats The freshman House Democratic phenom from New York offered top tips for Twitter.

Alexandria Ocasio-Cortez has been a member of Congress for only 15 days, but she already has some of the most veteran House Democrats chasing her heels and taking notes.

“Between [former Rep.] John Dingell and AOC, I’m going to get good at Twitter,” she said.

“AOC,” as the freshmen Democratic phenom from New York is known, has 2.44 million followers on Twitter. Rep. Dingell has nearly 37,000; her husband, John, has more than 251,000.

Ocasio-Cortez, the youngest woman in Congress, has electrified progressives with her social media engagement, unabashed about picking a fight, pushing back at critics and giving followers an inside look at her personal life.

“The top tip, I think, is really to be yourself and to really write your own tweets so that people know it’s you talking,” Ocasio-Cortez told ABC News after emerging from class.

ABC News was the only news organization to visit the Ocasio-Cortez Twitter boot camp in the bowels of the U.S. Capitol.

Here is a selection of the advice AOC gave to her peers:

“The way we grow our presence is being there.”
