In a stunning upset, Missouri Congresswoman Cori Bush, a prominent member of the progressive "Squad," has been defeated in her primary election by challenger Wesley Bell, the St. Louis County prosecutor. The loss marks the second defeat for a "Squad" member this election cycle, following the primary loss of New York Congressman Jamaal Bowman in June.

Bush, who rose to national prominence as an activist and organizer in the wake of the 2014 Ferguson protests, was first elected to Congress in 2020. However, her tenure has been marked by controversy, particularly surrounding her outspoken criticism of Israel's military actions in Gaza and her support for a ceasefire.

The primary race was one of the most expensive in the country, with outside groups pouring millions of dollars into the contest. Bell, who received significant backing from pro-Israel groups, criticized Bush's stance on Israel and accused her of being out of touch with the needs of her constituents.

In a statement following her defeat, Bush expressed disappointment but vowed to continue fighting for progressive causes. "This is not the end of our movement," she said. "We will continue to fight for justice, equality, and a better future for all."

Bell, meanwhile, celebrated his victory and promised to bring a new approach to the district. "I am humbled and honored to have the support of the people of Missouri's First District," he said. "I look forward to working together to build a brighter future for our community."

The loss of Bush is a significant blow to the progressive wing of the Democratic Party, which has seen its influence wane in recent years. It remains to be seen how the defeat will impact the party's direction and whether other "Squad" members will face similar challenges in the future.
