U.S. Rep. Alexandria Ocasio-Cortez and U.S. Sen. Bernie Sanders went out to breakfast in Burlington on Saturday.

Ocasio-Cortez, D-N.Y., and Sanders, I-Vt., were spotted by multiple social media users having breakfast at Penny Cluse Cafe with Sanders' wife Jane O'Meara Sanders and Sanders' campaign manager Faiz Shakir. Sanders wore a blue button-down shirt, and Ocasio-Cortez wore a red blazer, photos show.

Ocasio-Cortez, 29, is the youngest woman ever elected to Congress and a leader in the progressive wing of the Democratic party. She has not yet endorsed a presidential candidate, and the meeting Saturday revived rumors and speculation on her decision.

Penny Cluse attracts long lines on weekend mornings and is one of the most popular breakfast spots in town.

Former Vice President Joe Biden visited the restaurant in October 2016 with Sen. Patrick Leahy, Marcelle Leahy, and then-Democratic gubernatorial candidate Sue Minter.

Note: Sanders is an independent. His party affiliation was incorrect in an earlier version of this article.
