Paragraph: The Delaware State News reported Monday that Jessica Scarane plans to run against U.S. Sen. Chris Coons in the state's Democratic primary.

Coons said in a statement that he's proud to challenge President Donald Trump. But he also said he's someone who works across the aisle to "get done what we can in this environment to make our state and our community stronger." ___ Information from: Delaware State News, http://delawarestatenews.net Claim: Coons, US Senator from Delaware, will face primary challenge.
