Pittsburgh, Pennsylvania - Representative Summer Lee of Pennsylvania came out on top in her congressional primary race on Tuesday in a big win for the progressive Squad.

Lee secured over 60% of the vote in the Democratic primary to represent Pennsylvania's 12th congressional district, teeing her up for a second term on Capitol Hill.

"I am so humbled and proud to win my first primary re-election to be the congresswoman for this incredible district I’ve spent my life fighting for," Lee said in a statement after the race was called.

"Our campaign was built on a record of delivering for our democracy, defending our most fundamental rights, and expanding our vision for what is politically possible for our region’s most marginalized communities."

A popular progressive, Lee was up against conservative challenger Bhavini Patel, who described herself on the campaign trail as a "pro-Biden Democrat" and criticized the incumbent congresswoman's support for a ceasefire in Gaza.

Lee shot to the national spotlight in her 2022 primary as an influx of around $3.3 million from pro-Israel sources flooded the race in her opponent's favor. She won the election by less than 1,000 votes.

This cycle, the Moderate PAC – funded in large part by Republican megadonor Jeffrey Yass – dropped over $600,000 to support Patel.

The Mon Valley native's victory on Tuesday comes as the American Israel Public Affairs Committee has vowed to spend $100 million, via its United Democracy Project super PAC, in a bid to eject the Squad in 2024.

The general election for Pennsylvania-12 takes place on November 5, 2024, when Lee will take on Republican contender James Hayes.
