The journalist John Dickerson is a Washington creature to his core: a presidential historian, repository of political trivia, and scion of a glamorous Kalorama family whose party guests regularly included Kennedys, Johnsons and Reagans.
Now Mr. Dickerson, who until recently was better known as a writer than as the host of the CBS Sunday show “Face the Nation,” is leaving Washington and embarking on a new phase in his career: the Manhattan-centric world of morning TV.
CBS said on Tuesday that it had chosen Mr. Dickerson, 49, to replace Charlie Rose as the third co-host of “CBS This Morning,” a spot left empty since Mr. Rose was fired in November after allegations of sexual harassment. Mr. Dickerson is to join the lineup of Gayle King and Norah O’Donnell, who have carved a niche as a relatively serious, news-driven morning team.
Mr. Dickerson — whose mother, Nancy Dickerson, became in 1960 the first female correspondent at CBS News — plans to move to New York and leave “Face the Nation,” which he joined in 2015. CBS has not yet chosen his successor, effectively setting off a horse race at the network for one of television’s most influential political roles.
A genial on-air presence who speaks in a light Virginia accent, Mr. Dickerson has an understated style that belies a shrewdness honed by years of campaign and Washington reporting. Before joining CBS, he covered the George W. Bush administration for Time before moving on to write on politics for Slate.
He is among the few television journalists outside of Fox News who have interviewed President Trump in the Oval Office. Mr. Dickerson’s persistent questions — specifically about Mr. Trump’s unsubstantiated claim that his campaign had been wiretapped by the Obama administration — so agitated the president that Mr. Trump abruptly walked out of the room.
“CBS This Morning” calls more for genial banter than piercing interrogation: The show competes against sometimes syrupy juggernauts like “Today” on NBC and “Good Morning America” on ABC. But Mr. Dickerson was also expected to continue his political reporting.
“With John, Gayle, and Norah together we will be doubling down on serious news coverage,” the CBS News president, David Rhodes, wrote in a memo on Wednesday.
The addition of Mr. Dickerson is the second major recent shift in morning television. Last week, Hoda Kotb replaced the longtime morning host Matt Lauer, who was fired after allegations of workplace sexual misconduct, as the co-anchor for the opening hours of the “Today” show.
