WASHINGTON — Karine Jean-Pierre will make history by becoming the first Black woman, and first openly LGBTQ person, to hold the job of White House press secretary, President Biden announced on Thursday afternoon.

“Jill and I have known and respected Karine a long time and she will be a strong voice speaking for me and this Administration,” the president said in a statement.

Jean-Pierre will replace Jen Psaki, who was originally expected to serve for only the first year of Biden’s term. New coronavirus variants and the war in Ukraine kept her in the job for several months beyond that self-imposed limit.

“She is passionate. She is smart and she has a moral core that makes her not just a great colleague, but an amazing Mom and human. Plus, she has a great sense of humor,” Psaki said in a tweet.

“Representation matters. She will give a voice to so many, and show so many what is truly possible when you work hard and dream big. And that matters. And we should celebrate that,” Psaki said at the White House briefing on Thursday, while also touting Jean-Pierre’s resume. “But I also want to make clear what all of her qualifications are. … She comes to this job with decades of experience.”

Psaki’s last day on the job will be next Friday, May 13. She is expected to join MSNBC as an on-air commentator.

Jean-Pierre will take over the podium at a crucial phase in the Biden presidency, with the congressional midterms nearing and a presidential reelection campaign looming.

During the 2020 presidential primary, Jean-Pierre worked for the campaign of then-Sen. Kamala Harris. She has been at the White House since the start of the Biden administration.

The 44-year-old daughter of Haitian immigrants will inherit a position that attracted intense scrutiny during the Trump administration. Psaki has tried to keep the White House briefings free of the kinds of dramatics that, during the Trump years, turned some journalists into celebrities.

Biden praised Psaki for “returning decency, respect and decorum to the White House Briefing Room.”

Some thought the job might go to White House communications director Kate Bedingfield, who filled in capably while Psaki was home with COVID-19 last month. The war in Ukraine also raised the profile of Pentagon spokesman John Kirby, and he was also rumored to be under consideration.

Biden also announced that Anita Dunn, a trusted adviser who last year returned to the private sector, was rejoining the White House.
