“New party, who dis?” Ocasio-Cortez wrote on Twitter, suggesting that Lieberman’s glory days are long gone. The former vice-presidential nominee, who retired in 2013 after being a US Senator for 24 years, insisted that the Democrats will only be losing public support if they adopt, what he called, her “left-left” views as their own.

“I certainly hope she’s not the future and I don’t believe she is,” Lieberman told Fox Business Network when asked about Ocasio-Cortez’s role in the Democratic Party.

The newly-minted Congresswoman’s response was a paraphrase of a popular meme: “New phone, who dis?” Millennials often use such a response to avoid unwanted conversations through text messages by pretending they have no idea who is trying to contact them.

Ocasio-Cortez followers were there to applaud the tweet, supporting the idea of Lieberman and his views being out of date with even more jabs and memes.
