Democratic presidential nominee Hillary Clinton says Republican Donald Trump's gun rights comment incites violence and he does not have the temperament to be president.
"Every single one of these incidences shows us that Donald Trump simply does not have the temperament to be president and commander in chief of the United States," she said at a rally in Des Moines, Iowa, a day after Trump's remarks.
His remark at a Tuesday rally that gun rights activists could prevent Clinton from placing liberal justices on the US Supreme Court immediately sparked a torrent of criticism on social media that he was effectively calling for Clinton's assassination.
"If she gets to pick her judges, nothing you can do folks," Trump said at the rally at the University of North Carolina.
"Although the Second Amendment people, maybe there is, I don't know," he continued.
The US Constitution's Second Amendment guarantees a right to keep and bear arms.
Clinton's campaign called Trump's remark "dangerous".
Trump's campaign said the comment was misinterpreted and that he was encouraging gun activists to use their political power.
