State Sen. Wendy Davis of Texas will run for governor next year, two Democratic sources familiar with the planning confirmed to CNN.

The Democrat, who gained national fame after her 13-hour filibuster over a controversial abortion bill, was already scheduled to make an announcement about her political future on October 3.

But until Thursday it wasn’t certain whether she would be running for governor or run for re-election to her state Senate seat. Politico first reported Davis would run for governor.
