Homeland Security Secretary Markwayne Mullin has defended the Secret Service's response to a shooting at the White House Correspondents Association (WHCA) dinner, stating that agents prevented the gunman from breaching the second security perimeter. Cole Allen, 31, is accused of opening fire at the Washington Hilton hotel where senior Trump administration officials, including President Trump and Mullin, were gathered for the event. No one was injured during the incident. The WHCA dinner was cancelled after the shooting, but the event will be rescheduled within 30 days.
