Obama calls for moment of silence to honor victims Monday

President Obama called for a moment of silence on Monday to remember the victims of the Arizona shooting in which six were killed and 14 wounded, including Rep. Gabrielle Giffords (D-Ariz.).

“Tomorrow at 11:00 a.m. eastern standard time, I call on Americans to observe a moment of silence to honor the innocent victims of the senseless tragedy in Tucson, Arizona, including those still fighting for their lives," Obama said in a statement Sunday.

"It will be a time for us to come together as a nation in prayer or reflection, keeping the victims and their families closely at heart,” he said.

The Supreme Court will convene 10 minutes early to observe a moment of silence. U.S. District Judge John Roll was among those killed, the first federal judge to be killed since 1989.

Obama signed a proclamation Sunday ordering the American flag to be flown at half-staff at the White House and public buildings through Friday.

The flag will also be flown at half-staff at military installations and embassies abroad.

The president also postponed a planned Tuesday trip Schenectady, N.Y., to the General Electric energy division.

House Minority Leader Nancy Pelosi (D-Calif.) canceled a planned Monday trip to Detroit for the North American International Auto Show.
