President Obama has ordered the U.S. flag be lowered to half-staff as a mark of respect for the victims of the acts of violence committed Dec. 14 in Newtown, CT.

The flag must be flown at half-staff now until sunset, Tuesday, Dec. 18, 2012.

When flown at half-staff, hoist the flag to the peak for an instant and then lower it to the half-staff position. The flag should be raised to the peak again before it’s lowered for the day.
