The House is expected to adopt the FY 2013 GOP budget plan, which would set up a conflict with the Senate over appropriations spending levels. That chamber also plans a vote on a three-month highway bill extension, days before funding for transportation programs expires.
The Senate votes on a motion to invoke cloture on an oil and gas tax preference repeal measure and resumes consideration of its bill on tax rates for high-income earners.
If both chambers can agree on the transportation extension, they will likely leave town this afternoon to begin their 2-week recess period.
In other action in DC, the Supreme Court has concluded oral arguments on the constitutionality of the Affordable Care Act. They will now diliberate behind closed doors and offer their ruling sometime in June.
