The US Secret Service is facing questions after the shooting of Donald Trump on Saturday. A shooter climbed onto the roof of a building that was 130 metres from where Mr Trump was speaking at a rally. People at the event told police there was a man with a rifle on the building. There were also police inside the building. The director of the Secret Service said the shooting "was unacceptable". She said: "This is an event that never should have happened." She added: "The Secret Service is responsible for the protection of the former President. The buck stops with me."

The last assassination attempt in the U.S. was on President Ronald Reagan in 1981. Mr Trump was speaking to supporters at his campaign rally. The 20-year-old gunman fired eight shots. One bullet hit Mr Trump's ear. There was blood on his face. Secret Service officers immediately surrounded Trump. Secret Service staff rushed him to safety to a nearby car. One man died and two people were critically injured in the shooting. A sniper shot and killed the gunman. Mr Trump thanked God for "preventing the unthinkable". He was well enough to attend a convention on Monday.
