Republican Sen. Olympia Snowe says she plans to vote to confirm Elena Kagan as a Supreme Court justice.

The Maine lawmaker's announcement makes her the fourth Republican to break with her party to back President Barack Obama's high court nominee.

In a statement, Snowe says Kagan has met her standards for a justice with her strong intellect, respect for the rule of law and understanding of the Supreme Court's important but limited role.

She also says endorsements from conservative lawyers show that Kagan has a reputation for a sound judicial temperament.

Democrats have more than enough votes to confirm Kagan in a vote expected next week. Most Republicans oppose her, arguing she would bring a liberal bias to the bench.

After three days of testimony from former staffers, Allegheny County Judge Donna Jo McDaniel heard brief closing arguments and immediately ruled that the sisters were to stand trial on all charges.

Attorneys for both women said they were not surprised at the judge's decision but said they were confident of their chances at trial.

Jane Orie's attorney, William Costopoulous, called the evidence put forth by prosecutors as "trivial." He acknowledged staff members performed campaign work, but said they did so at their own volition or on compensatory time.

President Obama today called for a "practical, common sense" immigration system that will help the U.S. economy and maintain the steady flow of immigrants who have always enriched the United States.

"Such an approach demands accountability from everybody," Obama said during his first major immigration speech as president.

Obama said his administration has already taken record-setting actions to strengthen the border, and also urged Congress to approve "a pathway to legal status" for the 11 million or so illegal immigrants who are already here.

Speaking to lawmakers, academics, and community leaders gathered at American University, Obama stressed the contributions that immigrants have made and the discrimination they faced throughout U.S. history. "Immigrants have always helped to build and defend this country," Obama said.

Immigration has become "a source of fresh contention" in recent says because of new Arizona law that gives police greater authority to question people's citizenship, Obama said in his first major immigration speech as president. His administration is expected to file a lawsuit against Arizona, but the president did not discuss that plan.

President Barack Obama is turning his attention to energy and immigration legislation Tuesday.

He'll meet with a bipartisan group of senators to discuss passing comprehensive energy and climate legislation this year.

The president also will meet with members of the Congressional Hispanic Caucus to discuss the possibility of an overhaul of federal immigration laws — an iffy proposition in this election year.

Obama also will have a working lunch with King Abdullah of Saudi Arabia.

They span the ideological spectrum, including former clerks to Justice Antonin Scalia, the court's conservative icon, and to one of its most liberal stalwarts, former Justice William Brennan.

Vice presidential chief of staff Ron Klain is one of the signers, as are conservative lawyers Miguel Estrada and Peter Keisler, two of former President George W. Bush's failed judicial nominees.
