An estimated 1,900 troops are being deployed in D.C. More than half are coming from Republican-led states. Besides Union Station, they've mostly been spotted around downtown areas, including the National Mall and Metro stops.

Protesters booed and jeered Vice President JD Vance, Defense Secretary Pete Hegseth and White House deputy chief of staff Stephen Miller as they came to the station, located blocks from the U.S. Capitol, to thank the troops. The crowd's chants drowned out the voices of the officials.

As Vice President JD Vance staged a lunch to thank the National Guard members that President Donald Trump has deployed to Washington, DC, he was frequently drowned out by protesters.
