President Barack Obama is calling on people in the United States to observe a moment of silence at 11 a.m. EST Monday to honor victims of the Arizona shooting.
A White House statement says the moment of silence will allow people to come together, in prayer or reflection, and keep the victims and their families close at heart.
Obama will observe the moment of silence with White House staff on the South Lawn.
The president has signed a proclamation calling for flags to be flown at half-staff. The White House has postponed Obama's trip Tuesday to visit a General Electric energy division in Schenectady, New York.
