Rep. Lois Kolkhorst sent a letter requesting that the Attorney General of Texas issue an opinion addressing whether Texas voters were properly informed that approval of The Mobility Fund/Toll Equity Act of 2001 (Prop 15) involved more than just the establishment of the Texas Mobility Fund and the uses of that fund, but also included the use of any available revenue, including gas taxes, by TxDOT to grant money to toll roads without the requirement that it be repaid.
