Attack on Trump is the first assassination attempt on a US president since Reagan was shot in 1981.

(Patria) - The attack, carried out by a shooter who was killed by law enforcement officers, was the first assassination attempt on a US president or presidential candidate since Ronald Reagan was shot in 1981, AP reported.

Campaign dangers reached a new level after the assassinations of Robert F. Kennedy in California in 1968 and again in 1972 when Arthur Bremer shot and seriously injured George Wallace, who ran as an independent candidate on a campaign platform sometimes compared to Trump's.

This led to increased protection for candidates, although threats still existed, particularly against Jesse Jackson in 1988 and Barack Obama in 2008.

Presidents, especially after the assassination of John F. Kennedy in 1963, have an even higher level of security.

Trump's case is a rarity both as a former president and as a current candidate, AP writes.
