TPMDC's round up of the biggest initiatives on Capitol Hill:

• Health Care: House leaders delayed the release of their health care legislation for yet another day as they paper over differences with more conservative members of the Democratic party. Meanwhile, with President Obama back from abroad, the White House is wading in to the debate on the Hill like never before.
• Nominations: Supreme Court nominee Sonia Sotomayor appeared before the Senate Judiciary Committee on the first day of her week-long confirmation hearing. Sen. Jeff Sessions (R-AL) said her nomination could send the court down a "dangerous path". And Sen. Orrin Hatch (R-UT) lashed out at those who would dare criticize one of the New Haven firefighter's who's been recruited to testify against her.
