Richard Valeriani, an NBC News correspondent who was once clubbed by an ax-wielding assailant at a civil rights demonstration, earned the ire of the Johnson and Nixon White Houses for his television reporting and later worked on the other side of the camera, advising corporate executives and celebrities as a media consultant, died June 18 at his home in Manhattan. He was 85.

The cause was congestive heart failure, said his wife, Kathie Berlin.

As an NBC reporter from 1961 to 1988, Valeriani covered the Bay of Pigs invasion in Cuba, rallies for voting rights in the South, the globe-trotting diplomat Henry Kissinger and the U.S. response to the Iran hostage crisis under President Jimmy Carter.

He also worked as a Washington, D.C.-based correspondent for the Today show, the network’s flagship morning news program, although he expressed little pleasure in assignments that took him away from breaking news and scooping his competitors.

“I was sure that Dick Valeriani of NBC was sneaking around behind my back — and of course, he was! — getting stories that would make me look bad the next day,” the revered CBS reporter Charles Kuralt once said, explaining his turn in the 1960s from covering hard news to the offbeat subjects of his On the Road series.

Valeriani was NBC’s senior White House correspondent when he reported on an upcoming, then-secret 1967 summit between President Lyndon B. Johnson and Soviet Premier Alexei Kosygin, in a story that apparently led the president to unleash a fusillade of profanity.

“Johnson called him into his office at the White House and said, ‘There is no … way that you could know this if you are not (sleeping with) a Russian broad,” Berlin recalled. “And Dick said, ‘Mr. President, I’m a married person.’ And he said, ‘That doesn’t mean (anything) with you Italians.’ ” In a memoir, the former Soviet spymaster Oleg Kalugin — then working undercover as an embassy press attache — wrote that he was the one who told Valeriani about the meeting.

Valeriani later covered the Nixon administration during the Watergate investigation, and as a State Department correspondent traveled more than half a million miles with Kissinger, the national security adviser-turned-secretary of state.

The two men developed a warm relationship (according to Berlin, her husband turned down an offer to work as the diplomat’s spokesman), and in 1979 Valeriani published Travels With Henry, a breezy account of Kissinger’s approach to statecraft, fondness for junk food and rapport with members of the press corps.

“If it’s Thanksgiving,” Kissinger quipped during one long tour through the Middle East, according to Valeriani, “it must be Damascus.”

Although Valeriani spent most of his career in Washington, he said his most important work occurred in Mississippi and Alabama, where he helped bring images of peaceful civil rights demonstrators, tear-gas-filled streets and police attack-dogs to a national audience.

He became a part of the story himself on the evening of Feb. 18, 1965, while reporting on a voting rights march in Marion, Alabama, a short drive from Selma. “When I got there with my camera crew, I knew we were in trouble,” he told the Huffington Post in 2015. “Locals sprayed our camera lenses with black paint, and the Alabama state troopers assigned to provide security did nothing to prevent them.”

As demonstrators began marching to the county jail, the streetlights cut out. Valeriani was taking notes in near-darkness when law enforcement officers started attacking the protesters, and he was clubbed across the side of the head with the handle of an ax. Another journalist, United Press International’s Leon Daniel, later likened the sound to that of a watermelon being hit by a baseball bat.

“I remember a state trooper saying to the assailant, ‘You’ve done enough damage with this tonight,’ but he did not arrest him,” Valeriani recalled. “A white man came up to me and asked if I needed a doctor. I put my hand to the back of my head and looked at it; it was bloody. ‘Yeah,’ I said, ‘I think so.’ The man thrust his face up to mine and said, ‘We don’t have doctors for people like you.’ ”

A shaken Valeriani was hospitalized in Selma, where his NBC colleague Charles Quinn interviewed him for The Huntley-Brinkley Report, and received a get-well-soon telegram from Vice President Hubert Humphrey. The Associated Press later reported that his assailant, lumber salesman Sam Dozier, pleaded guilty to assault charges and was fined $78.75.

One black demonstrator at the rally, Jimmie Lee Jackson, was shot in the abdomen by a state trooper and died eight days later. His killing spurred the high-profile demonstrations and marches in Selma one month later, which Valeriani — fresh out of the hospital — covered for NBC.
