President Biden on Wednesday evening is set to deliver a speech at Union Station in the Capitol Hill neighborhood on democracy, where he will make clear what's at stake in the midterm elections.

Driving the news: “You can expect to hear from him this evening … there is a lot at stake including democracy and that everyone has a role in that," said White House Deputy Chief of Staff and Assistant to the President Jen O’Malley Dillon during an Axios News Shapers event on Wednesday.

• "The other thing that will be really important … people will be able to vote…democracy works to make sure every vote is counted."

The big picture: White House Senior Advisor and Assistant to the President Anita Dunn said that the setting of Capitol Hill is important.

• "Because on January 6th we saw violence geared towards subverting democratic processes there."
• "It is an appropriate place to make these remarks tonight," she said.
• "The threat of political violence ... it's something that unites almost all Americans and something we can all be united against," Dunn said.
