TPMDC's update on the biggest legislative initiatives on the Hill:

• Health Care: The Senate returns from recess this week with a tremendous amount of work to do if they plan to complete their work on health care reform by August recess. Key senators are beginning to suggest that the timeline may be too ambitious, but a spokesman for Sen. Majority Leader Harry Reid tells The Plum Line they should prepare themselves to work weekends if that's what it'll take to get the job done.
• Nominations: As conservatives and Republicans pore over documents relating to Supreme Court nominee Sonia Sotomayor's tenure on the board of the Puerto Rican Legal Defense and Education Fund, the Senate Judiciary Committee readies itself for a July 13 confirmation hearing.
• Senate Politics: After more than six months of waiting, Minnesotans will have their second senator tomorrow, when Sen.-Elect Al Franken is finally seated.
