President Donald Trump's press secretary Karoline Leavitt is expected to hold her first, official White House press briefing on Tuesday. 

The briefing is set for 1 p.m. EST. 

Leavitt, 27 is the youngest person to hold the position of White House press secretary.

Before her, the youngest press secretary was Ronald Ziegler who served under President Richard Nixon in 1969, according to The Associated Press.

During Trump's 2024 presidential campaign, Leavitt served as the national press secretary. In 2022, she ran unsuccessfully for Congress to represent New Hampshire's first congressional district. 

The press briefing will take place in the James S. Brady Press Briefing Room.
