In Iowa, school shooting prompts Republican prayers, while Trump campaigns by proxy

A school shooting in Iowa prompts prayers from Republican presidential candidates, but no substantial policy proposals. A sixth-grade student was killed and five people were wounded when a 17-year-old opened fire on the first day of classes. Florida Governor Ron DeSantis, locked in a close battle for second place in Iowa, said authorities have a responsibility to create safe environments but the federal government won't lead the effort. The incident highlights the strong support for gun ownership rights among Republican caucus-goers in Iowa.
