The idea to suspend the 18.4 cent federal gas tax and 24.4 cent diesel tax from Memorial Day to Labor Day was first proposed by McCain, the likely Republican presidential nominee, as a way to ease the economic burden for consumers during the summer.

Obama does not support the "gas tax holiday" and has said the average motorist would not benefit significantly from such a suspension; by some estimates, the federal government would lose about $10 billion in revenue.

"My opponent, Senator Obama, opposes giving consumers a break," Clinton said, campaigning in North Carolina. "I understand the American people need some relief."

Clinton said she would make up the difference in revenue by imposing a "windfall profits tax" on oil companies.

"If we suspended it and made up the lost revenues, that's the best of both worlds," she said.

Clinton commented at a firehouse in Graham, where she was urging North Carolinians to take advantage of the state's early voting, which opened more than a week ago ahead of the May 6 primary.

She and Obama have been pushing their supporters to go to the polls early here and Indiana, which also votes May 6. Obama is favored in North Carolina while the two are competing closely in Indiana.

Besides her push for early voting, Clinton was to spend part of the day raising money. She and daughter Chelsea were to appear at a closed-door fundraiser in Greensboro, with two more fundraisers scheduled later in Charlotte.

Obama also planned campaign appearances in the state, with events in Wilmington, Wilson and Chapel Hill.

Lawyers for defendant Brian Nichols said in court papers earlier this week that Superior Court Judge James Bodiford was quoted in a newspaper article four days after the March 11, 2005, shootings saying that he was friends with the judge killed in the rampage.

The article also said Bodiford released a statement at the time that described the death of Judge Rowland Barnes as a "brutal murder."

Nichols' lawyers questioned Bodiford's ability to be impartial, and asked that he step down.

Bodiford said at a hearing Thursday that he doesn't believe he should step down. But he said it's a good idea to let another judge review the issue.

Bodiford is serving on the Nichols case in place of a previous judge who stepped down from the case in late January after he was quoted in a magazine article saying of Nichols that "everyone in the world knows he did it."

Nichols' murder trial for the killings of four people resumes July 10.

James Battista told a judge in federal court in Brooklyn he hatched a scheme in late 2006 with another old friend of Donaghy, Thomas Martino, to pay the referee thousands of dollars for the information while Battista was "engaged in the business of sports betting."

Battista's lawyer had notified the court last week that his client wanted to go to trial rather than plead guilty to charges of defrauding the NBA, as Martino did earlier this month. But he changed his mind after prosecutors offered a last-minute deal allowing him to instead plead guilty to a lesser charge of conspiring to make illegal bets, said the lawyer, Jack McMahon.

"He's a gambler, and he bet," McMahon said. "We never really contested that."

The deal spares Donaghy from having to testify as the government's star witness at a high-profile federal trial. It also means Battista, 42, will face only 10 to 16 months in prison at sentencing on July 11. By contrast, Martino faces 12 to 18 months.

Donaghy, of Bradenton, Fla., pleaded guilty last year to charges he conspired to engage in wire fraud and transmitted betting information through interstate commerce.

The referee said he made NBA bets for four years, even wagering on games he worked. He also admitted recommending bets to high-stakes gamblers and collecting $5,000 if his picks hit.

Donaghy, 41, is scheduled to be sentenced May 22. By law, he faces up to 25 years in prison, though the term could be much lower under sentencing guidelines.

The South San Francisco-based biotechnology company was ordered to pay $500 million to a Southern California hospital for failing to pay royalties after City of Hope Medical Center helped manufacture some of its drugs.

A Los Angeles County Superior Court jury had awarded the hospital $300 million in actual damages and another $200 million in punitive damages for violating a contract signed in 1976.

The state's high court on Wednesday knocked out the $200 million in punitive damages but upheld the $300 million.

The closely watched case attracted 17 friends-of-the-court briefs from a variety of business interests.

The Supreme Court affirmed Wednesday that police have the power to conduct searches and seize evidence, even when done during an arrest that turns out to have violated state law.

The unanimous decision came in a case from Portsmouth, Va., where city detectives seized crack cocaine from motorist David Lee Moore after arresting him for a traffic ticket offense.

Justice Antonin Scalia said that when officers have probable cause to believe a person has committed a crime in their presence, the Fourth Amendment permits them to make an arrest and to search the suspect to safeguard evidence and ensure their own safety.

Moore was convicted on a drug charge and sentenced to 3 ½ years in prison. The Virginia Supreme Court had ruled police could not lawfully conduct a search.
