U.S. President-elect Donald Trump and his running mate, JD Vance, participated in a wreath-laying ceremony at Arlington National Cemetery Sunday.

Among those in attendance were his wife, Melania Trump, and his children: Donald Trump Jr., Eric Trump, Tiffany Trump and Ivanka Trump.

Also present were Pete Hegseth, his pick for defense secretary, Marco Rubio, his pick for secretary of state, Tulsi Gabbard, his pick for director of national intelligence and Elise Stefanik, his pick for United Nations ambassador. JD Vance’s spouse, Usha Vance, was also in attendance.

Trump appeared solemn as he placed a wreath on an easel at the Tomb of the Unknown Soldier. Moments later, Vance did the same.

Once the ceremony was complete, Trump’s motorcade headed to a separate section of the cemetery, a burial site for military personnel killed while fighting in Afghanistan and Iraq.
