Immediately after President Kennedy’s stretcher was wheeled into trauma room 1, Secret Service agents took positions at the door of the small emergency room. A nurse was asked to identify hospital personnel and to tell everyone, except necessary medical staff members, to leave the emergency room. Other Secret Service agents posted themselves in the corridors and other areas near the emergency room. Special Agent Lawson made certain that the Dallas police kept the public and press away from the immediate area of the hospital.[C2-250] Agents Kellerman and Hill telephoned the head of the White House detail, Gerald A. Behn, to advise him of the assassination. The telephone line to Washington was kept open throughout the remainder of the stay at the hospital.[C2-251] Secret Service agents stationed at later stops on the President’s itinerary of November 22 were redeployed. Men at the Trade Mart were driven to Parkland Hospital in Dallas police cars.[C2-252] The Secret Service group awaiting the President in Austin were instructed to return to Washington.[C2-253] Meanwhile, the Secret Service agents in charge of security at Love Field started to make arrangements for departure. As soon as one of the agents learned of the shooting, he asked the officer in charge of the police detail at the airport to institute strict security measures for the Presidential aircraft, the airport terminal, and the surrounding area. The police were cautioned to prevent picture taking. Secret Service agents working with police cleared the areas adjacent to the aircraft, including warehouses, other terminal buildings and the neighboring parking lots, of all people.[C2-254] The agents decided not to shift the Presidential aircraft to the far side of the airport because the original landing area was secure and a move would require new measures.[C2-255] When security arrangements at the airport were complete, the Secret Service made the necessary arrangements for the Vice President to leave the hospital. Unmarked police cars took the Vice President and Mrs. Johnson from Parkland Hospital to Love Field. Chief Curry drove one automobile occupied by Vice President Johnson, U.S. Representatives Thomas and Thornberry, and Special Agent Youngblood. In another car Mrs. Johnson was driven to the airport accompanied by Secret Service agents and Representative Brooks. Motorcycle policemen who escorted the automobiles were requested by the Vice President and Agent Youngblood not to use sirens. During the drive Vice President Johnson, at Youngblood’s instruction, kept below window level.[C2-256] Removal of the President’s Body
