Former progressive Squad member Cori Bush attempts political comeback against Missouri US Rep. Bell

Former U.S. Rep. Cori Bush is attempting a political comeback Tuesday in a Missouri Democratic primary that tests evolving views on American-Israeli relations, just two years after the progressive "Squad" member was ousted by voters in favor of Wesley Bell.

The rematch in a heavily Democratic St. Louis district is one of several consequential primaries. In western Missouri, Republicans are picking a candidate to try to unseat Democratic Rep. Emanuel Cleaver in a dramatically reshaped district that is part of President Donald Trump's attempt to retain a slim House majority in the midterms.
