Donald Trump's campaign spokesperson has denied allegations that the Republican presidential nominee had advocated the assassination of his Democratic rival Hillary Clinton. In a speech on Tuesday, Trump suggested that gun owners or those backing gun rights could stop Clinton from winning the White House and picking new US Supreme Court justices."Hillary wants to essentially abolish the Second Amendment," Trump told a rally in Wilmington, North Carolina on Tuesday, referring to the US Constitution's clause that enshrines the rights of Americans to bear arms. "If she gets to pick her judges, nothing you can do folks," Trump said. "Although the Second Amendment people - maybe there is, I don't know."Votes not violenceIt was not immediately clear exactly what Trump meant by his remarks, but US media and social media users quickly expressed concern that Trump was promoting that Clinton or the judges could be assassinated. "It's called the power of unification - 2nd Amendment people have amazing spirit and are tremendously unified, which gives them great political power," senior Trump communications advisor Jason Miller said."And this year, they will be voting in record numbers, and it won't be for Hillary Clinton, it will be for Donald Trump." 'Dangerous' languageBut Clinton campaign manager Robby Mook blasted Trump for using "dangerous" language."A person seeking to be the president of the United States should not suggest violence in any way," Mook said.The Republican nominee has repeatedly bashed his Democratic opponent for seeking to abolish gun rights. "Was @realDonaldTrump suggesting his supporters shoot Hillary? Shoot her nominee? Who knows. It's all so disgusting and embarrassing and sad," Murphy tweeted."This isn't play. Unstable people with powerful guns and an unhinged hatred for Hillary are listening to you, @realDonaldTrump," Murphy tweeted.
