A White House spokesman says the president has been informed about the shooting outside a contest for Prophet Muhammad cartoons in suburban Dallas and believes no act of expression justifies violence.
Spokesman Josh Earnest says extremists try to use expressions they consider to be offensive as a way to justify violence around the world.
Earnest says "there is no act of expression, even if it's offensive, that justifies an act of violence."
Earnest also praised the officers who responded to the Sunday night shooting, saying "we saw a pretty important and notable display of bravery on the part of first responders."
The two gunmen, armed with assault rifles, were killed after opening fire on officers outside the event. One security guard was wounded.
Earnest credits officers' courage for the incident not resulting in more injuries or deaths. Â (AP)
