Sander Vanocur, who for decades has covered the greatest moments of US politics for NBC and ABC news, has passed away.

Chris Vanocur tells The Associated Press that his father died Monday night in Santa Barbara, California. He was 91.

As a national policy correspondent to the NBC in the 1960s, Vanocur covered conventions, elections, and assassinations during some of the most memorable years in American history.

He was an interlocutor during the first debate between John F. Kennedy and Richard Nixon in 1960 and continued to cover Kennedy with the White House administration.

He also reported on Vietnam and civil rights, including a long interview with Martin Luther King, Jr.

Vanocur also interviewed Robert F. Kennedy two days before he was murdered in Los Angeles in 1968.
