Beto O’Rourke, the former Texas Democratic congressman, onetime Senate candidate, and past presidential candidate, kept his powder dry Sunday on whether he’ll mount a campaign for Sen. John Cornyn’s (R-TX) seat next year.

“I don’t know,” O’Rourke said on CNN’s State of the Union. “Right now, I’m holding these town halls all over the state of Texas, across the country to listen to people to bring them together and to channel our anger into action, registering people to vote, organizing with voters right now.”
