Attorney General Janet Reno is reviewing whether to reopen the investigation of civil rights leader Martin Luther King Jr.'s assassination based on new evidence presented by his widow.

Coretta Scott King spent two hours Wednesday at the Justice Department laying out her evidence and questions for Reno. She said Reno listened "very sympathetically."Afterward, Reno said, "We will carefully review the questions and information they presented, and I will be in touch with them as soon as the review is complete."

"We presented new evidence that has come to our attention about the assassination of my husband," Coretta King told reporters afterward. She said the evidence included "new witnesses coming forth that had never been investigated" but declined to elaborate.

She said she proposed a national commission with the power to subpoena evidence, to grant immunity and to prosecute, "because all this evidence needs to be presented to an official body."

She was accompanied by her son, Dexter, former U.N. Ambassador Andrew Young and former District of Columbia congressional delegate Walter Fauntroy. Reno brought Deputy Attorney General Eric Holder and Associate Attorney General Raymond Fisher and other aides to the meeting.
