After decades without political violence directed at a presidential candidate from one of the major parties, the US has now experienced this twice in the space of two months - with former president Donald Trump the target on both occasions.
In mid-July, he narrowly avoided being shot in the head by a gunman at a rally in Butler, Pennsylvania. The 20-year-old attacker was shot dead by a sniper.
Two months later, on Sunday afternoon, during a round of golf, he was the apparent target of another would-be assassin, according to the FBI, with a suspect now in custody.
Something approaching 10% of US Presidents have been assassinated. Add in a couple more attempts, and there really isn’t much special about these days.
