NYC Mayor Orders Rainbow Lights on City Hall

In the wake of the mass shooting in Orlando, New York City Mayor Bill de Blasio on Sunday ordered all flags to be flown at half-staff, and said City Hall will be lit up with rainbow colors at sunset. The accused shooter, Omar Mateen, killed 50 people and injured at least 53 others at a gay nightclub before he died in a gun battle with police. It is the deadliest mass shooting in U.S. history.
