DENVER (AP) — Labor rights figure Lily Ledbetter is in Colorado to campaign for President Obama.

Ledbetter will attend an educator's breakfast Saturday and the opening of a campaign office in south Denver. She is campaigning with Democratic National Committee Chairwoman Debbie Wasserman Schultz.

Ledbetter's name is on the first bill signed by Obama when he took office in January 2009. The Lily Ledbetter Fair Pay Restoration Act gives workers more time to file pay discrimination lawsuits. Ledbetter was a supervisor at a Goodyear Tire & Rubber Co. plant in Gadsden, Ala., who sued her company after learning she earned less than male supervisors. She won her lawsuit, but the U.S. Supreme Court in 2007 threw out her complaint, saying she failed to sue with the 180-day deadline.
