In a full-page ad in the Dallas Morning News, “Major Republican donors, including some who have contributed to Gov. Greg Abbott’s campaigns, joined other conservative Texans in signing an open letter supporting congressional action to increase gun restrictions in response to the mass shooting in Uvalde that left 19 children and two teachers dead last week.” The letter “endorses the creation of red-flag laws, expanding background checks and raising the age to purchase a gun to 21. More than 250 self-declared gun enthusiasts signed it.”
