The resolution calls for a one-minute moment of silence starting at 1 p.m. Eastern Time on Sept. 11, and calls on everyone to cease all work or other activities. It also encourages people to mark the moment "in an appropriate manner, including by ringing bells, blowing whistles or sounding sirens."

It specifically calls on media outlets, airlines and airports, sports teams, all levels of government, schools and other organizations to observe the moment of silence.

The resolution was introduced by Sen. Frank Lautenberg (D-N.J.) and is co-sponsored by seven other Democrats, Sen. Joe Lieberman (I-Conn.) and Sen. Pat Toomey (R-Pa.).
