Rep. Alexandria Ocasio-Cortez (D-NY) and former House Speaker Nancy Pelosi (D-CA) have had several tense moments in their nearly five years serving in Congress together, according to a new book.

Ocasio-Cortez, part of the group of House progressives referred to as the "Squad," and Pelosi, a longtime Democratic leader in the lower chamber of Congress, butted heads several times since the New York Democrat upset longtime Rep. Joe Crowley in the Democratic primary for the Empire State's 14th Congressional District, according to excerpts given to the Guardian from the new book The Squad: AOC and the Hope of a Political Revolution by journalist Ryan Grim.

Grim writes in the book that their first "live meeting" was in San Francisco, California, in July 2018, and Pelosi reportedly talked for "nearly the entire lunch."

“Getting Pelosi’s unfiltered thoughts was both eye-opening and disturbing,” Grim wrote, according to the outlet. “Ocasio-Cortez, who had made the slogan ‘Abolish Ice’ [U.S. Immigration and Customs Enforcement] central to her challenge to Crowley, was particularly perplexed to hear Pelosi say that the phrase had been injected into American political discourse by the Russians and that Democrats needed to quash it."

The New York Democrat was also reportedly upset with Pelosi that no one from the Democratic Congressional Campaign Committee had asked how she was able to unseat Crowley. Ocasio-Cortez claims in the book that Pelosi "got so mad at me” when she discussed how the party should "pay attention and ask questions" when upsets happen to "spot weaknesses."

The report also cites text messages the author has from Ocasio-Cortez, with one discussing the nearly 50-year age gap between the two House Democrats.

“The amount of times she told me that stupid ‘I have protest signs older than you in my basement’ s***. Like yeah but mine don’t collect dust,” a text from Ocasio-Cortez that Grim cites said.

The outlet also reports that the New York Democrat has seen less hostility since Pelosi stepped down as Democratic House leader last year, adding that "senior members talk to me, [committee] chairs are nice to me, people want to work together," according to the book.

Pelosi stepped down as Democratic leader in the lower chamber of Congress after the 2022 election, but she has remained a member of the House of Representatives and is running for reelection to her San Francisco seat in 2024. Rep. Hakeem Jeffries (D-NY) succeeded Pelosi as Democratic leader.
