Toomey said he’d introduce the resolution when Congress returns to work Tuesday afternoon.
Rep. Richard Nugent (R-Fla.) is sponsoring the House companion measure, H.Res. 503.
The resolution would state the sense of the Senate that "abandoning the search efforts for members of the armed forces who are missing or captured in the line of duty now or in the future is unacceptable."
It also states that "while the United States is beginning the strategic withdrawal of forces from Afghanistan, the United States must continue to fulfill these important promises to any member of the armed forces who is in a missing status or captured as a result of service in Afghanistan now or in the future."
