Congress to Review Security During Closure Next Week

Even though Congress has decided to close for normal business this week, the Capitol Police will be reviewing security as they worry about possible copycats from the public shooting of Democratic Rep. Gabrielle Giffords in Arizona on Saturday, sources tell CBS News.

While Congress will be closed for business, President Barack Obama has ordered all flags on government buildings be flown at half-mast tomorrow, and called for a national moment of silence at 11 a.m., Eastern Time.

"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," Obama said in a statement.

A conference call was scheduled for Sunday with U.S. Capitol Police, the House Sergeant at Arms Office and House members and spouses, reports the website Politico.

Security officials in Capitol Hill say the move is purely precautionary.

"There are no immediate or actionable threats to members or the Capitol complex," Senate Sergeant at Arms Terry Gainer told Politico.

Some members of Congress want to review ways in which extra security details could be added during their public appearances, while others say guarding all 535 members of Congress all the time is impossible and a waste, Politico reports.

Rep. James Clyburn (D-S.C.), told The Hill newspaper that he believes the House may need to add funding to individual's budgets in order to beef up security.

Clyburn also said the shooting is more evidence that the Transportation Safety Administration needs to stop treating congressmen like ordinary citizens in airports.

"The fact of the matter is, we are held to a higher standard in so many other areas, and I think we need to take a hard look at exactly how the TSA interact with members of Congress," Clyburn said.
