Before joining Newsom's campaign, Demissie previously served as Booker's campaign manager in 2013, when Booker was first elected to the Senate.

"I could not be more lucky to have @just_jenna with me on this campaign. A true superstar talent (and just wait until you hear some of the others folks @CoryBooker's got on board!)," Demissie tweeted Friday, confirming his appointment.

Hey, that’s me.

Booker has also started staffing up in early primary states, KTLA reports, making several hires from House Democratic campaigns and one pickup from former Maryland Gov. Martin O'Malley's (D) 2016 presidential campaign in Iowa.

The junior New Jersey senator announced his campaign Friday morning, coinciding with the beginning of Black History Month.

"The history of our nation is defined by collective action; by interwoven destinies of slaves and abolitionists; of those born here and those who chose America as home; of those who took up arms to defend our country, and those who linked arms to challenge and change it," he said in an announcement video.

Booker joins an already crowded field of 2020 Democratic primary contenders, including fellow Sens. Elizabeth Warren (D-Mass.), Kirsten Gillibrand (D-N.Y.) and Kamala Harris (D-Calif.).
