AUSTIN— Texas House Democrats are urging Gov. Greg Abbott to call a special session to increase public school funding, while Abbott is criticizing them for opposing legislation last year that tied increased funding to his pet project — school vouchers. The Austin American-Statesman reported the Democrats sent a letter, written by Rep. Jon Rosenthal, D-Houston, calling for a 30-day special session focused on both increasing per-student funding and investing more in school safety.
