The Latest on Texas attack: White House says much to investigate in Islamic State claim

1 p.m. CDT

The White House says intelligence officials had a lot to investigate related to the Islamic State group claim of responsibility for a shooting at a Texas cartoon contest that featured images of the Prophet Muhammad.

Press Secretary Josh Earnest said Wednesday analysts want to review whether the claim is accurate and at what level the Islamic State group may have known about the plan. He says they want to determine if the two men who opened fire at the Dallas-area contest and were fatally shot by authorities were in contact with the group.

A federal law enforcement official has said authorities had an open investigation into one of the men. The official said investigators will study the contacts the men had in the U.S. and abroad.
