House and Senate members, scheduled to return to the Capitol on Thursday, have spent most of the last two weeks divided on a key part of the plan to invest about $900 million more for highways. Senate officials, in passing their version of the funding plan earlier this month, demanded a minimum amount of money guaranteed for the state's economic stabilization fund, known as the rainy day fund. House lawmakers fought against a floor in their plan, which the Senate rejected last week.
Wednesday, Perry's office said he would call a third special session if lawmakers fail to act. Transportation funding is the final issue of this session unresolved. The session wraps up on Tuesday.
