A candidate for the Abilene, Texas, City Council said that three churches made an honest mistake by donating to his campaign and that he is returning the money. The race has been beset by allegations of electioneering by churches.

The majority of the state’s 19 mass shootings over the past six decades were carried out by men who legally possessed firearms, an investigation by ProPublica and The Texas Tribune found.

State lawmakers have rejected dozens of bills that would have prevented people from legally obtaining weapons used in many mass shootings. Instead, they’ve made it easier for residents to get guns and harder for local governments to regulate them.
