NBC News has learned that President Obama intends to nominate Elena Kagan to the US Supreme Court, to succeed Justice John Paul Stevens.
She is currently a senior Justice Department official -- the first woman to be solicitor general, the nation's top courtroom advocate.
She was also the first woman dean of Harvard Law School. And she taught at the University of Chicago, where she met a young Barak Obama.
And if confirmed, she'd be the court's fourth woman justice -- and the third to currently sit on the court.
Officials say the president will make the announcement tomorrow morning at the White House.
