The Senate returns at 9:30 a.m. for speeches, and at noon will consider the nomination of David Petraeus to be director of the CIA. His confirmation is expected to sail through the Senate; Majority Leader Harry Reid (D-Nev.) praised Petraeus on Wednesday night as the "most noted soldier" of the last 50 years.

Two hours of debate are scheduled for the nomination, and the vote is scheduled for 2 p.m.

After that, more debate on a Republican proposal for a balanced-budget amendment to the Constitution is possible. Senate Republicans on Wednesday called up a joint resolution on this amendment, and can be expected to continue pushing for its adoption over Democratic objections.

The Senate is also considering remaining in session during the July 4 week in order to continue working on a debt-ceiling agreement. President Obama said Wednesday that Congress should "stay here until we get it done."
