Washington: The supporters of US Republican nominee Donald Trump shoved and pushed journalists, including an NDTV reporter, outside an event venue in Pennsylvania, calling them "liars" and threatening to "knock the mic down", a media report said on Saturday.
"I don't want to talk to media, you are liars," a supporter shouted at the NDTV reporter, "I will knock your mic down. Who the hell are you, whoever knows you," he yelled.
Subsequently the police intervened, NDTV reported.
The incident occurred shortly after the business magnate had addressed around 5,000 people in Pennsylvanian administrative division of Newton.
Trump has taken anti-media attacks to a new level, accusing journalists of being in cahoots with his Democratic rival Hillary Clinton's campaign in a conspiracy to rig the election.
In Pennsylvania, a key swing state in the US elections, Trump is trying to be the first Republican since 1988 to win the state which carries 20 electoral votes; 270 are needed to win.
In August at a rally in Fairfield, Connecticut, Trump had said, "I am not running against Crooked Hillary Clinton, I'm running against the crooked media".
Trump has complained for months about media coverage which he said is biased against him.
He had stripped a long list of news organisations -- including the New York Times, Buzzfeed, Politico and the Washington Post -- of their credentials, and vowed that as the President he would make it easier to sue news outlets.
However, he later allowed them to cover his events.
The business mogul's campaign for the November 8 election has been scrambling to recover from the release of 2005 video in which he bragged about groping women and making unwanted sexual advances. Since then, many women have come forward with similar allegations.
Clinton is leading Trump by 12 percentage points, according to a new national poll, up 8 points from a similar survey conducted last month.
The Monmouth University poll released earlier this week put Clinton ahead of Trump, 50 per cent to 38 per cent, Politico news magazine reported.
The former Secretary of State's lead was up significantly from the 4-point advantage she held in September's Monmouth poll.
This latest poll is the first to be conducted entirely since the accusations of sexual assault against Trump began to emerge.
