    They signed up to fight for their country, and the state of Texas promised to pay for their education.
    For decades, veterans went to public universities and colleges under the Hazlewood Exemption, which kicks in after federal benefits under the G.I. Bill are exhausted. But the price tag has increased sevenfold since 2009, when legislators in Texas — which has the country's second-highest veteran population, 1.7 million — allowed the benefit to be passed on to veterans' children under a legacy provision.
    "Everybody's heart was in the right place when we added all the other beneficiaries," said Republican Sen. Kel Seliger, chair of the Senate's higher education committee. But, he added, "it just got too high of a price tag."
    Now, amid rising legacy costs and concern that a federal lawsuit over residency could push the benefit's annual figure to $2 billion, policymakers must carefully balance state politics and fiscal conservativism with commitments made to veterans during World War II.
    Of the 10 states with the most veterans, only Illinois and Texas waive all tuition and fees for veterans who meet program requirements, according to a Texas Legislative Budget Board report. And Texas is the only state of the 10 to offer full tuition and fee waivers to children, the report said, a decision made in 2009 in tandem with expanding the benefit to include spouses of veterans who were injured, missing or killed in action.
    About 39,000 Texas residents used the benefit last fiscal year, at a cost of $169 million, according to the Texas Legislative Budget Board. That's 576 percent more than before the legacy expansion, when only about 10,000 used the exemption at a cost of nearly $25 million.
    Most of the cost of the program falls to the higher education institutions, other than $11.4 million from a new state fund that dispersed Hazlewood reimbursement money this fiscal year.
