Officials familiar with Obama's deliberations say other people are also being discussed, including names that have not triggered public speculation.

Among those Obama is considering are Solicitor General Elena Kagan, Michigan Gov. Jennifer Granholm, Homeland Security Secretary Janet Napolitano and U.S. Appeals Court judges Sonia Sotomayor and Diane Pamela Wood. California Supreme Court Justice Carlos Moreno is also under review by Obama.

Sources familiar with Obama's deliberations confirmed the names to The Associated Press on condition of anonymity because no candidates have been revealed by the White House. The confirmation amounts to the first time any name has been directly tied to Obama.

More candidates may be added to the list as Obama considers a replacement for retiring Justice David Souter. The president's review process is expected to intensify in the coming days, with a decision expected by or near the end of May.

Kilpatrick Stockton LLP, an Atlanta-based firm, confirmed in a statement that attorney Mark Levy had died.

"Mark Levy was well known and highly respected for his successful appearances before the Supreme Court of the United States," said Bill Dorris, the firm's co-managing partner.

Levy was a deputy assistant attorney general in the Department of Justice between 1993 and 1995 and served five years in the Solicitor General's office.

D.C. Police spokeswoman Helen Andrews said officers were called to an office building where the firm is located to investigate a shooting Thursday morning. Investigators believe it was a suicide.

Levy attended Yale University's law school with former President Bill Clinton and Secretary of State Hillary Clinton and more recently worked on fundraising for Hillary Clinton's presidential campaign, said Dennis Gingold, an attorney who was working with Levy on a case.

"I don't know anyone who isn't shocked by what just happened," Gingold said. "He was a good guy. He really was ... and professionally, he was first class."

During his career, Levy had argued 16 cases before the Supreme Court. At Kilpatrick Stockton, he served as counsel and chair of the firm's Supreme Court and appellate advocacy practice. Levy, who was married and has two children, lived in Bethesda, Md.

He also suggested longer school days — and years — to help American children compete in the world.

In his first major speech on education, Obama said the United States must drastically improve student achievement to regain lost international standing.

"The future belongs to the nation that best educates its citizens," he said. "We have everything we need to be that nation ... and yet, despite resources that are unmatched anywhere in the world, we have let our grades slip, our schools crumble, our teacher quality fall short and other nations outpace us."

His solutions include teacher pay and charter school proposals that have met resistance among members of teachers unions, which constitute an important segment of the Democratic Party.

Obama acknowledged that conflict, saying, "Too many supporters of my party have resisted the idea of rewarding excellence in teaching with extra pay, even though we know it can make a difference in the classroom."

Despite their history on the issues, union leaders publicly welcomed Obama's words, saying it seems clear he wants to include them in his decisions in a way President George W. Bush did not.

More than four months after Election Day, Minnesota voters are only marginally closer to knowing whether Democrat Al Franken or Republican Norm Coleman will represent them in Washington.

The stakes go beyond Minnesota: Franken would put Democrats in position to muscle their agenda through with barely any Republican help, and he could be a difference-maker on the federal budget and a proposal giving labor unions a leg up on management when organizing.

Some Minnesotans, like actor Jared Reise, are past caring who wins and just want the state to regain its second senator.

"This is a very important time to have everybody there, with the way the economy is," said Reise, of suburban Eagan, who didn't vote for either man on Nov. 4. "It's a little long-winded, this whole recount."

The statewide recount ended two months ago, with Franken ahead by 225 votes out of 2.9 million cast. Coleman had held a similar sized lead heading into the recount. The campaigns are now arguing in a special court whether the latest tally is accurate.

Ginsburg is recovering from surgery for pancreatic cancer, her second major bout with cancer. She returned to the court on Monday.

A loud cheer went up in the House chamber when Ginsburg was seen entering.

Also in attendance were Chief Justice John Roberts and Justices Samuel Alito, Stephen Breyer, Anthony Kennedy and Clarence Thomas.

Three other justices — Antonin Scalia, David Souter and John Paul Stevens — were absent.

While technically not a State of the Union address, Obama's speech in essence serves as the more formal talk to Congress this year. Breyer has not missed one since 2001, while Roberts and Alito have been to every one since they joined the court in 2005 and 2006.

Justices typically have said little about why they do or don't attend the speech. One exception is Scalia, who hasn't gone in at least 10 years. He has said the speech has become increasingly partisan, a problem for a group that studiously refrains from applauding even remotely political statements.

The court will announce whether it has accepted any cases for review, dispose of hundreds of rejected appeals and hear arguments in cases at a session that should end around noon.

Ginsburg had surgery for pancreatic cancer on Feb. 5. She was released from the hospital eight days later and has said she intends to be in court Monday.
