New Jersey Democrat Robert Menendez will lead the tour Monday, which will include a helicopter flight to Long Beach Township.
Louisiana's two U.S. senators are scheduled to be part of the delegation.
The tour comes days after President Barack Obama asked Congress for $60.4 billion in federal aid for New Jersey, New York and other states hit by Sandy.
The measure blends aid for homeowners, businesses, and state and local governments. Whether it passes this month or gets delayed in whole or part until next year is unclear.
