President Obama on Tuesday nominated federal appellate Judge Sonia Sotomayor to the U.S. Supreme Court.

Sotomayor "is an inspiring woman who I believe will make a great justice," Obama said at a White House announcement.

She "has worked at almost every level of our judicial system, providing her with a depth of experience and a breadth of perspective that will be invaluable as a Supreme Court justice," he added.

Obama said Sotomayor would bring more experience on the bench than anyone currently serving on the Supreme Court when appointed.

"Thank you, Mr. President, for the most humbling honor of my life," Sotomayor said. She thanked family members and mentors who helped her throughout her life and career.

The president met with Sotomayor at the White House for an hour Thursday, according to senior administration officials.

He was impressed with Sotomayor's personal story and professional qualifications after meeting her, but he did not immediately offer her the job, two senior administration sources added.
