There is no love lost between US President Donald Trump and Hillary Clinton. During the run up to the US Presidential Elections 2016, Trump and Clinton had a number of verbal spats. The nature of duel between them, which is a unique characteristic of the US Presidential polls, had touched a new nadir. From time to time, two of the most influential persons in the world have taken pot shots at each other. Going a step further on Sunday, Trump too another dig at his bitter Democratic rival, by retweeting a doctored video showing him swinging a golf club and appearing to hit Clinton with a golf ball. The animated GIF (Graphics Interchange Format) image shows Clinton tripping and falling after being hit in the back as she boards a plane in 2011 as the secretary of state. The tweet has caught fire on Twitter as 63,000 people have liked it and 29,000 people retweeted it. The tweet also drew flak with many people on social media saying that the president is not fit for the office. The White House did not respond to a request for comment about the tweet. A spokesperson for Clinton also declined to comment, according to reports.

"The President of the United States just retweeted a video vignette that imagines him assaulting his political rival. The man is unfit," tweeted Shaub, who joined the ethics office as a staff attorney early during the George W Bush administration and was appointed as the office's director by President Barack Obama. The tweet came as Trump is preparing for a critical round of powerhouse diplomacy with world leaders at the United Nations. Last week, Clinton promoted her new book, "What Happened," about her experiences as the Democratic party's nominee for president of the US in the 2016 election. She lost the presidential race to Trump. Trump slammed Clinton over her new book earlier this week too, tweeting that she "blames everybody (and everything) but herself for her election loss."
