Sen. Kyrsten Sinema of Arizona, who is now an independent, is considering a 2024 reelection bid after Democratic Rep. Ruben Gallego jumped into the race.

Chris Coons discussed U.S. aid being given to Ukraine following Russia’s invasion while Joe Manchin called for American energy independence, an attendee said.

Sinema said in a tweet she was declaring her “independence from the broken partisan system in Washington and formally registering as an Arizona Independent.”
