SAN MARCOS, Texas -

Fresh off a much-publicized chat with President Barack Obama, Democratic gubernatorial candidate Wendy Davis is addressing an annual teachers' gathering.

The state senator from Fort Worth is appearing with Leticia Van de Putte, a San Antonio state senator and the Democratic lieutenant governor hopeful.

Both will speak at the Texas State Teachers Association convention in San Marcos on Saturday.

Davis met briefly with Obama on Thursday while the president was in Austin for a civil rights summit honoring the accomplishments of President Lyndon Johnson.

Education has been a key issue in the Texas governor's race, where Davis is considered an underdog against Republican Attorney General Greg Abbott.

Davis and Abbott have both called for expanding pre-kindergarten statewide, but differ on the best way to do so and the costs associated.
