QUANTICO, Va. — President Donald Trump and Defense Secretary Pete Hegseth are expected to address hundreds of generals and admirals Tuesday in Quantico, Virginia, in an unusual and urgent in-person meeting called by Hegseth last week, CBS reports. Watch full: Defense Secretary Pete Hegseth addresses senior military officialsDefense Secretary Pete Hegseth addresses senior military officialsHegseth began his speech around 8:15 a.m., ahead of Trump, who spoke after 9 a.m. The nation's top military leaders from all over the world were summoned last week by Hegseth to travel to Virginia for a meeting with the defense secretary but were initially given no information about why. Senior military commanders meet regularly throughout the year in person, but a meeting of this magnitude with so little warning or indication about its purpose is rare, if not unprecedented. Hegseth said senior military leaders need to end the "poisonous culture of risk aversion."
