Hundreds of mourners said their last goodbyes to Charlie Kirk on Sunday during a memorial at the Kennedy Center in Washington, D.C. Donald Trump was not in attendance, but his Secretary of Health and Human Services, Robert F. Kennedy Jr., was.

RFK Jr. gave a speech where he paid tribute to the late conservative political influencer, who was fatally shot last Wednesday in Utah. But one detail had people talking, as the health secretary made a bizarre claim about his and Charlie’s past.

Charlie Kirk’s death has stunned America. The conservative media pundit was fatally shot during an event at Utah Valley College last week, and after a 33-hour manhunt, the primary suspect, 22-year-old Tyler Robinson, turned himself in.

Vigils for Charlie Kirk have been held nationwide. A memorial service is scheduled for Sunday, September 21, in Glendale, Arizona, at State Farm Stadium. During the previous weekend, a vigil was held at the Kennedy Center, attended by many politicians.
