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 NelsonBill NelsonA guide to the committees: Senate Senate advances Trump's Commerce pick CMS nominee breezes through confirmation hearing 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. Sherrod BrownSherrod BrownSanders, not Trump, is the real working-class hero A guide to the committees: Senate House bill would prevent Trump from lifting Russian sanctions MORE (D-Ohio) and Debbie StabenowDebbie StabenowA guide to the committees: Senate Trump's pick to lead Medicare won't say if she supports negotiating prices with drug companies Overnight Finance: Fed chief tries to stay above partisan fray | Bill would eliminate consumer agency | Trump signs repeal of SEC rule on foreign payments MORE (D-Mich.) are proposing an amendment that would extend a health insurance tax credit under the Trade Adjustment Assistance program.

Other amendment proposals have nothing to do with either the FAA or healthcare. One from Sen. David VitterDavid VitterMercury brings on former Sen. Vitter, two others Lobbying World Bottom Line 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 SchumerDean: Schumer's endorsement 'kiss of death' for Ellison How the candidates for DNC chair stack up ahead of Saturday's vote DNC candidate Harrison drops out, backs Perez for chairman 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. This is an apparent reaction to some passenger complaints that security images have been distributed.

Another from Sen. Jerry MoranJerry MoranYahoo reveals new details about security A guide to the committees: Senate Verizon, Yahoo slash merger deal by 0M over data breaches MORE (R-Kan.) would require the secretary of Defense to report on any unfair competitive advantage that might have existed in the context of contract awards for the KC-X aerial refueling program. One amendment from Sen. John Ensign (R-Nev.) would expand direct flight service to Reagan National Airport.
