Democratic Rep. Sean Casten will win his party’s nomination for Illinois’ 6th Congressional District, CNN projects.

Casten defeated another incumbent, Rep. Marie Newman. Casten has served two terms in Congress after flipping his district in the Chicago suburbs in 2018.

The seat, created in last year’s redistrict process, was an awkward fit for both incumbents: Newman lives outside the new district, while Casten lives in it. But more of Newman’s constituents from the district she currently represents are in the new 6th District, while most of Casten’s current constituents were shifted into another district. 

Newman was in her first term but is facing a House Ethics Committee investigation into allegations that she may have promised federal employment to a primary challenger in exchange for their political support. Newman has denied the allegations and has said the complaints were politically motivated.

Newman was elected to Congress in 2020, when she ousted Rep. Dan Lipinski, one of the party’s most conservative House members at the time. 

A pro-Israel group had advertised against Newman, criticizing her for voting against $1 billion to fund Israel’s Iron Dome rocket defense shield last year.
