The Senate on Tuesday swiftly approved six members of President Barack Obama's Cabinet, but it put off for a day the vote on his choice to be secretary of state, Hillary Clinton.
The Senate confirmed all six with a single voice vote a little more than three hours after Obama took the oath of office to become the 44th president.
Those confirmed were Steven Chu to be energy secretary, Arne Duncan at education, Janet Napolitano for homeland security, Eric Shinseki to head veterans affairs, Ken Salazar for interior and Tom Vilsack to lead the department of agriculture.
The Senate also approved Peter Orszag, recently the director of the Congressional Budget Office, to head the White House's Office of Management and Budget.
Democratic hopes to add Clinton to that list were sidetracked when one senator, Republican John Cornyn of Texas, objected to the unanimous vote.
Cornyn said he still had concerns about foreign donations to the foundation headed by Clinton's husband, former President Bill Clinton.
Senate leaders agreed to have a roll call vote on Clinton on Wednesday after three hours of debate. Jim Manley, spokesman for Senate Majority Leader Harry Reid, predicted that "she will receive overwhelming bipartisan support at that time."
The Wednesday vote became necessary when Cornyn objected to the voice vote. In the Senate, a single senator can block measures from being approved by voice.
He said he wanted "a full and open debate and an up-or-down vote on Sen. Clinton's nomination." He said important questions remain unanswered concerning the foundation headed by the former president "and its acceptance of donations from foreign entities. Transparency transcends partisan politics, and the American people deserve to know more."
Cornyn spokesman Kevin McLaughlin said the senator is not trying to block her confirmation but is seeking more debate on the donation issue.
Several Republicans raised questions at Clinton's confirmation hearing about possible conflicts of interest from Bill Clinton's fundraising work and his acceptance of large donations from foreign countries and companies.
Also left unconfirmed were several other top members of Obama's Cabinet. Timothy Geithner, the nominee to head the Treasury Department, faces the Finance Committee Wednesday, where he will have to explain his initial failure to pay payroll taxes he owed while working for the International Monetary Fund.
The Judiciary Committee is expected to vote as early as Wednesday on Eric Holder to be attorney general. Also still in the confirmation process is former Senate Democratic leader Tom Daschle, Obama's pick to head health and human services and spearhead his efforts to reform health care.
Robert Gates, who has served as defense secretary under President George W. Bush, will continue in that position in the Obama administration.
The Senate traditionally moves quickly to affirm the new president's Cabinet.
Eight years ago the Senate approved seven members of President George W. Bush's Cabinet, including Colin Powell to be secretary of state.
On Bill Clinton's first day in office in 1993, the Senate gave the go-ahead for the secretaries of state, defense and the Treasury. They next day it approved eight more Cabinet officers.
