President Donald Trump has issued a proclamation ordering American flags to be flown at half-staff in honor of the victims killed in Thousand Oaks, California on Wednesday night.
Twelve people were killed by a suspect who is a former U.S. Marine. Another 10-12 were wounded. The shooter took his own life, authorities said in a news conference on Thursday.
The mass shooting took place in a bar called Borderline where many college students were hanging out and patrons were dancing. It was country music night at the bar.
Trump called lowering the flags "a mark of solemn respect."
