President Obama is ordering flags on public buildings and grounds to be flown at half-staff until Tuesday following the deadly mass shooting at a community college in Oregon.
American flags will be lowered at the White House and public buildings and military installations across the country as well as at U.S. embassies and posts abroad.
Obama delivered his proclamation shortly after he finished a press conference at the White House where he discussed the school shooting for the second time in two days.
His presidential proclamation is intended as "a mark of respect for the victims of gun violence perpetrated" Thursday at Umpqua Community College in Roseburg, Ore.
Obama first responded to the Oregon shooting that left nine people dead, along with the lone gunman, and several more injured, during a press conference on Thursday evening.
“This is a political choice that we make, to allow this to happen every few months in America,” a visibly angry Obama said then. “We collectively are answerable to those families who lose their loved ones because of our inaction.”
Many Republicans have pushed back on calls for new gun measures in the wake of the shooting, while Democrats called for an end to the "carnage" of mass shootings.
Obama last ordered flags to fly at half-staff at the White House and other federal buildings on the anniversary of the 9/11 attacks and following a July shooting that left five U.S. services members dead in Chattanooga, Tenn.
Obama's proclamation came shortly after the names of the shooting victims were released by the Douglas County Sheriff's Office. The victims ranged in age from 18-67.
