The Texas state senator who made headlines with her nearly 13-hour filibuster against a strict abortion bill earlier this year has decided to run for governor in 2014, sources confirm to Fox News.

Sen. Wendy Davis, D-Fort Worth, intends to file her paperwork for the race Wednesday or Thursday of next week, the sources say.

The 50-year-old mother of two’s filibuster at the Texas Capitol temporarily blocked new statewide abortion restrictions from being passed in June.

The abortion bill, which was eventually signed into law by Gov. Rick Perry, requires doctors to have admitting privileges at nearby hospitals, allow abortions only in surgical centers, limits where and when women may take abortion-inducing pills and ban abortions after 20 weeks.

Davis’ filibuster drew hundreds of supporters to the Texas state capitol and won her pro-choice admirers nationwide. She even drew a mention from President Obama's campaign Twitter account.

No other Texas Democrats have entered the governor's race. Republican Attorney General Greg Abbott announced his candidacy this summer and is the early favorite to succeed Gov. Rick Perry.
