The Senate has voted 78-to-22 to confirm John Roberts as the 17th chief justice of the United States.
All of the Senate's majority Republicans and about half the Democrats voted for Roberts.
The 50-year-old U-S Appeals judge will succeed William Rehnquist, who died earlier this month.
The White House plans to swear him in this afternoon.
Before the vote, Majority Leader Bill Frist said the Roberts court will face "some of the most difficult and fundamental questions of U.S. law."
Roberts watched the Senate vote on T-V from the White House. He
and his wife are having lunch with President Bush and the first lady. Then, there will be a swearing-in ceremony, so Roberts can be in place when the new court session begins on Monday.
