He was 93.
Schorr died Friday at Washington's Georgetown University Hospital after a brief illness, said his son, Jonathan Schorr.
Daniel Schorr's career of more than six decades spanned the spectrum of journalism - beginning in print, then moving to television where he spent 23 years with CBS News and ending with National Public Radio, where he worked until he died. He also wrote several books, including his memoir, "Staying Tuned: A Life in Journalism."
Schorr, who was born in New York City to Russian-Jewish immigrant parents, reported from Moscow; Havana; Bonn, Germany; and many other cities as a foreign correspondent. While at CBS, he brought Americans the first-ever exclusive television interview with a Soviet leader, Nikita Khrushchev, in 1957.
During the Nixon years, Schorr not only covered the news as CBS' chief Watergate correspondent, but he also became part of the story. Hoping to beat the competition, he rushed to the air with Nixon's famous "enemies list" and began reading the list of 20 to viewers before previewing it. As he got to No. 17, he discovered his name.
"I remember that my first thought was that I must go on reading without any pause, or gasp or look of wild surmise," he wrote in his book "Clearing the Air." "I do not know how well I carried off my effort to appear oblivious to the discovery of my name on an ominous-looking list, but I count this one of the most trying experiences in my television career."Schorr's stories pointing out weaknesses of the administration's programs so angered Nixon that he ordered an FBI investigation of the reporter - saying he was being considered for a top federal job. That investigation was later mentioned in one of the three articles of impeachment - "abuse of a federal agency" - adopted by the House Judiciary Committee against Nixon.
At the time, Schorr called it "an inescapable decision of journalistic conscience" to see that the report ended up in print.
To his surprise, reaction from his own colleagues in the media was negative, because Schorr had handed the report over in exchange for a donation to a group that aids journalists in First Amendment issues.
Many reporters also found Schorr's silence troubling when another CBS correspondent, Lesley Stahl, was wrongly accused of leaking the report.
Schorr was suspended by the network and the House opened an investigation, though it later dropped the case. He resigned from CBS soon after.
Well into his 90s, he was still giving commentaries on NPR.
He was last heard on the air waves July 10, on NPR's "Weekend Edition" with Scott Simon in a discussion of the U.S.-Russia spy swap, the Justice Department's lawsuit against Arizona and other news of the week.
Former CBS colleague Dan Rather said: "In Washington, he prided himself on being an outsider, not an insider. He didn't work the social circuit. He worked his shoe leather and his telephones."
