White House Press Secretary Karoline Leavitt announced significant changes to White House briefings to allow for influencers and podcast hosts to apply for media credentials.

WASHINGTON (AP) — Karoline Leavitt, the youngest person to serve as White House press secretary, will make her debut in the briefing room on Tuesday. Her first briefing is scheduled for 1 p.m. ET.

Leavitt can claim a first of her own — at age 27, she is the youngest White House press secretary in history — though she hopes to become better known for her ability to speak for and defend the Trump administration.
