U.S. Defence Secretary Pete Hegseth is expected to field sharp questions from members of Congress about his tumultuous start as Pentagon chief, including his sharing of sensitive military details over a Signal chat, in three separate Capitol Hill hearings beginning Tuesday (June 10, 2025).

Lawmakers also have made it clear they are unhappy that Mr. Hegseth has not provided details on the administration's first proposed defence budget, which President Donald Trump has said would total $1 trillion, a significant increase over the current spending level of more than $800 billion.
