Texas Republican Gov. Greg Abbot has invited state lawmakers from both parties, top education officials and experts on school marshal programs and school architecture and design to the first of three roundtable discussions on curbing future school shootings.

Tuesday's initial discussion will be held at Abbott's state Capitol office. He has pledged to subsequently hear from advocates on all sides of the gun debate, as well as victims of a November mass shooting at a church in the town of Southerland Springs.

Abbott said the goal is to seek "solutions to make our schools more secure and to keep our communities safe."

Rep. Chris Turner, head of the Democratic Caucus in the Texas House, said in a statement Monday: "While discussions to generate consensus are welcome, we believe we also have a responsibility to act immediately."
