As a result of her high profile, Ocasio-Cortez's unabashed takes on congressional life have frequently come under fire.
Eddie Scarry, a writer for the Washington Examiner, disputed Ocasio-Cortez's account of her financial hardships based on her clothing choices.
"Hill staffer sent me this pic of Ocasio-Cortez they took just now," Scarry tweeted. "I'll tell you something: that jacket and coat don't look like a girl who struggles." The tweet has since been deleted after widespread backlash.
Rep. Sean Duffy, R-Wis., condemned the media for what he viewed as preferential treatment in coverage of Ocasio-Cortez. As a freshman congressman in 2011, Duffy received negative reactions after telling a constituent that he struggles to pay his bills.
"Hmm which headlines and article does media give to GOP and which to a Dem?" Duffy tweeted alongside screenshots of articles referencing himself and Ocasio-Cortez.
Last week, Donald Trump Jr., the president's eldest son, shared a doctored image on Instagram in which Ocasio-Cortez asks, "Why are you so afraid of a socialist economy?" In the post, President Trump responds, "Because Americans want to walk their dogs, not eat them." Trump Jr. captioned the meme "It's funny cuz it's true!!!"
Ocasio-Cortez fired back, tweeting: "Please, keep it coming Jr – it's definitely a 'very, very large brain' idea to troll a member of a body that will have subpoena power in a month." Democrats have made clear that they plan to use their new subpoena power in the House to further investigate potential Russian interference in the 2016 elections.
The representative-elect has also received praise for revealing parts of the political system that are typically left in the shadows.
Actress Kerry Washington, who stars in the political drama "Scandal," commended Ocasio-Cortez's behind-the-scenes revelations, tweeting, "@Ocasio2018 speaking truth to power. Sharing the NEEDED #BTS of our democracy at work. So grateful."
"I'm learning more details about how the House actually works over the past two weeks than I ever did in the past 20 years," one follower tweeted in reply to Ocasio-Cortez.
"Thank you so much for giving us the window into the inside baseball of Congress," another follower said.
Paul Musgrave, assistant professor of political science at University of Massachusetts Amherst, praised Ocasio-Cortez on Twitter for "treating voters as neither super-sophisticated DC insiders, nor as people who can't be trusted to make up their own minds, but rather as people who are curious and intelligent but who aren't experts in DC process."
"Sometimes," he added, "you don't need a new theory of politics to make change, just a willingness to state the obvious."
