A vote to repeal the health care law passed during the last session is expected occur Wednesday.

An amendment to repeal the law sponsored by Minority Leader Mitch McConnell, R-Ky. flew onto a Federal Aviation Administration spending bill Tuesday afternoon. The measure is identical to a bill that passed the House in January. It would require 60 votes in order to be adopted, and while McConnell says all 47 members of his caucus are on board, it is unclear how much support the bill has amongst the Democratic majority.

The Senate Judiciary Committee holds a hearing on the constitutionality of the Affordable Care Act. The massive legislation has been subject to lawsuits from parties all across the United States, with varying results. Most recently, a Florida district judge ruled that the individual mandate provision in the law, which requires people to purchase health insurance or pay a fine, is unconstitutional. The committee will investigate the matter with a state attorney general, a legal scholar who supports the overhaul, and one prominent critic of the law, Georgetown University Law Professor Randy Barnett.

House Democrats vehemently opposed the repeal, but were powerless to stop it. They'll hold a press event alongside state and local government officials, as well as trade association and union representatives at 1 p.m. ET to show their support for the bill.

Another less controversial health care amendment also got added to the aviation bill. Sen. Debbie Stabenow, D-Mich., authored a provision to repeal the requirement that businesses must file 1099 tax forms for every vendor with whom they have at least $600 in transactions. Removing the provision has widespread support; the only question is whether the Stabenow language or another similar bill will eliminate the reporting regulation.
