"Midnight Cowboy" star Voight, who has supported several Republican politicians over the years, said on Twitter that Trump's remarks to "Access Hollywood" host Billy Bush in 2005 "were not as damaging as De Niro's ugly rant. Trump's words did not hurt anyone," reported Fox News.
"I am so ashamed of my fellow actor Bobby DeNiro's rant against Donald Trump. What foul words he used against a presidential nominee, who has worked harder then any other man I know in the past year and a half to get a good message to the American people," Voight, 77, tweeted.
"Donald Trump's words were not as damaging as Robert DeNiro's ugly rant. Trump's words did not hurt anyone. Can you imagine if any Republican said words like Robert DeNiro used - against Hilary Clinton or Barack Obama? All hell would break loose," he wrote.
He further posted, "I am calling for all Trump supporters to express their outrage and anger against DeNiro and all of the Republican turncoats cont'd against Trump. Let Donald Trump know we are completely behind him, and may God give him the strength to continue his calling."
"I'd like to punch him (Trump) in the face," he had said in a video clip.
