The ceremony marked a major moment for Gov. Greg Abbott, who threw his full political weight and millions of campaign dollars into a push for school choice.

Gov. Greg Abbott has signed the $1 billion controversial school choice bill into law, allowing for taxpayer money to be used to help qualifying students pay for private school tuition. "Today is the culmination of a movement that has swept across the state and our country," Abbott said Saturday.

The front lawn of the Governor’s Mansion was packed with state and federal lawmakers, families and students as the governor put pen to paper on legislation years in the making.
