Rockefeller is expected to continue to allow amendments to be submitted this week and possibly into next week before finalizing an agreement with Republicans on which amendments will come up for a vote.

Democrats allowed two healthcare amendments to the FAA bill yesterday; one to repeal the healthcare law was rejected, but one to end an IRS tax reporting requirement was accepted. Still, the Senate may still have to decide whether to consider other healthcare amendments to the FAA bill.

Sen. Bill NelsonClarence (Bill) William NelsonOvernight Health Care: Ryan's office warns he wasn't part of ObamaCare deal | House conservatives push for mandate repeal in final tax bill | Dem wants probe into CVS-Aetna merger Ryan's office warning he wasn't part of deal on ObamaCare: source Overnight Health Care: Funding bill could provide help for children's health program | Questions for CVS-Aetna deal | Collins doubles funding ask for ObamaCare bill MORE (D-Fla.) has proposed an amendment to the FAA bill that is a sense of Congress asking the Supreme Court to decide on whether the healthcare law is constitutional. Yesterday, Nelson said a prompt Supreme Court decision would help prevent Congress from continuing to fight about the law.

Also related to healthcare, Sens.

Other amendment proposals have nothing to do with either the FAA or healthcare. One from Sen. David VitterDavid VitterThe Senate 'ethics' committee is a black hole where allegations die Questions loom over Franken ethics probe You're fired! Why it's time to ditch the Fed's community banker seat MORE (R-La.) would require the U.S. government to prioritize old age, survivors' and disability pay through the Social Security Administration in the event that the government reaches its debt limit later this year. This is similar to an amendment from Sen. Pat Toomey (R-Pa.) that would ensure that government payments on interest on U.S. debt takes priority in the event that the U.S. reaches its debt limit.

Each of these amendments indicate that a decision to extend the U.S. debt limit may be difficult to reach, as several Republicans are arguing that the U.S. should cut government spending rather than raise the debt ceiling.

Several pending amendments are FAA-related and could be taken up next week. One from Sens. Ben Nelson (D-Neb.) and Charles SchumerCharles (Chuck) Ellis SchumerAmerica isn't ready to let Sessions off his leash Schumer celebrates New York Giants firing head coach: ‘About time’ GOP should reject the left's pessimism and the deficit trigger MORE (D-N.Y.) would require criminal penalties to be applied to anyone who makes an unauthorized recording of security screening images or distributes those images.

One amendment from Sen. John Ensign (R-Nev.) would expand direct flight service to Reagan National Airport.
