Washington (CNN) – 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.
Her campaign has remained tight lipped to the press about her upcoming public decision. Her spokesman, Hector Nieto, did not confirm–but also didn't deny–reports that she was putting her hat into the gubernatorial ring.
"All I can say...is that Senator Davis told her grassroots supporters last week via email she has made a decision and she looks forward to making her decision public on October 3," he told CNN. But advisers have reached out privately to Democrats to inform them of her decision. But advisers have reached out privately to Democrats to inform them of her decision, according to sources.
After her filibuster–which delayed a vote on a bill meant to ban most abortions for pregnancies past 20 weeks and implement strict regulations on abortion clinics–Davis found herself on the national stage and a potential hope for Democrats in Texas who want to turn the state blue.
Given the attention she drew over the filibuster, speculation soon followed that she may challenge Gov. Rick Perry in 2014, but the longtime Republican governor announced this summer he won't be seeking re-election next year.
Republican Greg Abbott, the state's attorney general, has already started running for the office, and is considered the leading GOP candidate.
Democrats haven't won a gubernatorial election in Texas since Ann Richard's victory in 1990.
