Rep. Dean Phillips launches primary challenge against Biden

• A moderate who flipped a Republican district in 2018, Phillips served as a member of House Democratic leadership this year.

Driving the news: Phillips filed to run with the Federal Election Commission and launched a website, Dean24.com.

• "A campaign built on joy and bringing people together," the website says, calling supporters the "DeanTeam."

The backdrop: Phillips has been a lone voice in the Democratic Party making the case against Biden’s re-election for more than a year, pointing to the president’s age and polling that shows Democratic voters want an alternative.

• Over the summer he began teasing a bid of his own, while simultaneously urging more high-profile Democrats to get into the race.
• Frustration towards Phillips’ comments among his Democratic colleagues precipitated his resignation as co-chair of the Democratic Policy and Comittee earlier this month, which was first reported by Axios.
