(CNN) - Glen Johnson, the political editor for the Boston Globe's website, has long covered Sen. John Kerry of Massachusetts–and he'll continue to follow the veteran senator right into the State Department.
Johnson announced Thursday that he's leaving journalism to work as a senior adviser for Kerry when the senator takes on his job as U.S. Secretary of State once his resignation takes effect Friday.
"My duties will include traveling with the secretary and assisting him as he represents President Obama and the administration abroad and at home," Johnson wrote in a farewell email.
Johnson, 50, has been working as a news reporter for 27 years. He said his upcoming work with Kerry will be "reminiscent of our travels from 2001 until 2003, as the senator laid the groundwork for his 2004 presidential campaign and I tagged along for The Boston Globe."
Kerry eventually went on to become the 2004 Democratic presidential nominee.
The senator sailed through his confirmation hearings last week and was confirmed by the Senate on Tuesday.
It's certainly not unusual for journalists to cross over into the realm of public service. White House Press Secretary Jay Carney, for example, served as the Washington bureau chief for Time Magazine before becoming communications director for Vice President Joe Biden in 2008. Chuck Hagel, who's undergoing his Defense Secretary confirmation hearings Thursday, worked as a radio newscaster and talk show host in Nebraska before working for a U.S. congressman.
And who can forget Sarah Palin, who worked as a sportscaster in Anchorage, Alaska before moving on to Wasilla City Council and later becoming mayor, then governor.
As for Kerry, he told the Globe he thinks "the world of Glen and the path he's traveled as a shoe leather reporter."
"He's not a partisan," he continued. "He just cares about the quality of our dialogue and he cares about our country and he'll contribute to both of them. I'll be lucky to have him at my side in this endeavor."
In his farewell speech Wednesday, Kerry gave special mention to the journalists who cover Congress.
"I thank the reporters who catch us in the hallways, trap us, ambush us in the hallways, despite all the changes and challenges in their own business, still dutifully document the first drafts of American history," he said. "I thank all the incredible people who travel through these halls working incredibly hard to get it right, people of character who cover this place as a public service not a sport – and I thank them."
