Republican senators, including a member of the Senate’s leadership, accosted the director of the Secret Service in a suite at the Republican National Convention on Wednesday night, demanding that she resign or provide a full explanation for the security lapses that led to the near-miss assassination attempt against former President Donald J. Trump. Senators John Barrasso of Wyoming, the third-ranking Senate Republican, and Marsha Blackburn of Tennessee aggressively confronted the agency’s director, Kimberly A. Cheatle, at Fiserv Forum in Milwaukee. A staff member for one of the senators videotaped the confrontation and sent it to a reporter. “You put him within less than an inch of his life,” Mr. Barrasso said to Ms. Cheatle, almost yelling. “So resignation or full explanation.”
