Trump supporters heckle Robert De Niro's wild Biden campaign conference

Robert De Niro has been brutally heckled during his appearance at a Joe Biden campaign conference outside of the Manhattan courthouse holding Donald Trump's criminal trial. The 80-year-old actor said the former president wants to "destroy" New York City and aims to eventually destroy the "entire world". De Niro was confronted by angry Trump supporters who labelled him a "washed-up actor" as they heckled him following the speech. He was then mocked on social media by critics of the Biden campaign.
