Multiple senators chase down, jeer Secret Service director at RNC

Multiple Republican senators chased down U.S. Secret Service Director Kimberly Cheatle after they spotted her at the RNC on Wednesday.

Tennessee Sen. Marsha Blackburn was one of the senators and shared a video of the confrontation on her X page, where she accused Cheatle of "stonewalling" them as she refused to respond to their repeated jeers.

"This was an assassination -- you owe the people answers, you owe President Trump answers," Blackburn can be heard saying in the video.

Multiple sources, who verified the authenticity of the video, told ABC News that the Secret Service director was on the suite level of the convention hall.

Blackburn was joined by Sens. John Barrasso, James Lankford and Kevin Cramer in confronting the director at the convention. Their move is unprecedented.

"He calls me during the middle of the school day to ask how my golf game is going and tells me all about his. But then I have to remind him that I'm in school and I will have to call him back later," she said. "When we play golf together, if I'm not on his team, he will try to get inside of my head. And he is always surprised that I don't let him get to me. But I have to remind him, I'm a Trump, too."

Kai, 17, the daughter of Donald Trump Jr., addressed Trump's legal troubles, saying, "Even when he is going through all of these court cases, he always asks me how I'm doing."

She said she was "shocked" to hear about Saturday's assassination attempt.

"It was heartbreaking that someone would do that to another person," she said. "A lot of people have put my grandpa through hell and he's still standing. Grandpa, you are such an inspiration and I love you."
