Senior Republican figures gathered at the Kennedy Center in Washington on Sunday evening to pay tribute to conservative activist Charlie Kirk who was fatally shot at a college in Utah.

Upon entering the Concert Hall, a large screen hung at the back of the stage, showed clips of Kirk’s speeches and events, as well as news reports and interviews.

With House Speaker Mike Johnson, Health Secretary Robert Kennedy, Jr. and an array of White House officials in attendance, each official paid their respects to the late conservative activist.

“We all felt it deep, deep inside and in spite of that, we remember that our dear friend Charlie would never want us to be overcome by despair,” said Mike Johnson.

“Charlie fundamentally believes in the potential and the promise of so many in this room. Young, patriotic Americans, and he inspired millions of us across the country to get off the couch and to enter the political arena to fight for our nation's conservative values,” said Karoline Leavitt, the White House Press Secretary.

Kirk also was memorialized at Dream City Church in Phoenix, where he hosted one of his “Freedom Night in America” gatherings.

Flowers, US flags and handwritten messages were also left at a makeshift memorial at Utah Valley University’s main entrance.

Turning Point USA, Kirk's conservative organization, will hold a memorial for him Sept. 21 at State Farm Stadium outside Phoenix, where the Arizona Cardinals play.

Kirk's casket arrived on Thursday in his home state aboard Air Force Two, accompanied by Vice President JD Vance.
