A progressive congresswoman made history in 2022. Can a billionaire stop her re-election?

Summer Lee, Pennsylvania's first Black congresswoman, has expanded her base on the left. Her primary is a test case in a year progressive candidates face a challenge from pro-Israel funds

The US representative Summer Lee greeted a cheering crowd of a couple of hundred supporters at the Pittsburgh teachers' union headquarters on Sunday, with two days left until her Democratic primary.

Lee, who made history in 2022 when she became the first Black woman elected to Congress from Pennsylvania, predicted that voters would send a resounding message on Tuesday about the resilience of the progressive movement. To underscore that point, Lee was joined at the rally by Representative Alexandria Ocasio-Cortez of New York, another member of the progressive Squad" in the House.
