I’m running for Congress because the people of Missouri’s 2nd District deserve a representative who will stand up for them. I’m running because those in charge in Washington are sacrificing our nation’s values, along with the people they’re supposed to serve. I’m running because this is my home.

We can return leadership, courage, and accountability to Washington. Through listening and open dialogue, I’m driven to create bipartisan solutions that protect and improve the lives of all Missourians. I’m committed to Medicare for All, common sense gun safety reforms, keeping unions strong for working families, and ending the wars in Iraq and Afghanistan. We can elect leaders who put people first. I hope you’ll join me.
