Democrats say the bill is needed because women still earn 77 cents for every dollar men earn for the same job. But Republicans say the bill goes overboard in trying to police fair wage laws, including by seeking salary information from companies, but also by being vague enough to make companies unsure of what pay differences are legal.

Assuming the 2:15 p.m. vote fails, the Senate could move quickly to consider a five-year farm bill.

The House returns at noon for speeches, then later in the afternoon will debate 10 suspension bills, with votes at 6:30 p.m.

Most are land-use bills, although one of them would implement an international treaty under which participating countries would help each other locate parents who owe child support elsewhere.

The suspension bills are:

H.R. 2060 - Central Oregon Jobs and Water Security Act,

H.R. 2336 - York River Wild and Scenic River Study Act,

H.R. 1740 - To amend the Wild and Scenic Rivers Act to designate a segment of Illabot Creek in Skagit County, Wash., as a component of the National Wild and Scenic Rivers System,

H.R. 3263 - Lake Thunderbird Efficient Use Act,

H.R. 241 - To authorize the conveyance of certain National Forest System lands in the Los Padres National Forest in California,

H.R. 2512 - Three Kids Mine Remediation and Reclamation Act,

H.R. 4222 - To provide for the conveyance of certain land inholdings owned by the United States to the Tucson Unified School District and to the Pascua Yaqui Tribe of Arizona,

S. 363 - A bill to authorize the secretary of Commerce to convey property of the National Oceanic and Atmospheric Administration to the City of Pascagoula, Miss.,

S. 292 - Salmon Lake Land Selection Resolution Act,

H.R. 4282 - International Child Support Recovery Improvement Act.
