Along the way, the House should also take up S. 3187, the Food and Drug Administration Safety and Innovation Act, as amended by the House. Both chambers have approved similar bills, and GOP leaders have scheduled a suspension vote to consider this amended version.

Members should also vote on a motion to instruct conferees to the highway bill to complete their work by Friday, and debate another motion from Rep.

The Senate returns at 9:30 a.m., after having disposed of a few dozen amendments to the farm bill on Tuesday. But the Senate will start Wednesday with more debate and a vote on a motion to proceed to a resolution disapproving of the Environmental Protection Agency's rule on emission standards for mercury and air toxins.

A successful vote on S.J.Res. 37 would lead to 10 hours of debate, but the vote is expected to fail, after which the Senate will continue work on amendments. The vote on the resolution is expected at around 11:30 a.m.

After that, back to the farm bill. Forty-five of 73 farm bill amendments remain, and Senate leaders indicated late Tuesday that six of those might be considered by voice vote.
