Rep. Ilhan Omar's primary today is latest test for "Squad" members

Rep. Ilhan Omar is the latest "Squad" member to face a primary that could be close, following the high-profile defeats of Reps. Jamaal Bowman of New York and Cori Bush of Missouri. 

For the second time in two years, Omar faces a challenge from former Minneapolis City Council member Don Samuels. Omar narrowly beat Samuels in 2022 with a slim margin of roughly 2,500 votes. 

"I'm feeling very, very excited," Samuels told CBS News. "Last time it was difficult. People were asking, 'Why are you doing this? You can't win.' And so there was a lot of hedging of efforts and bets and a little bit of reluctance and it required persuasion. This time people are understanding that if they had invested we could have won."
