In the latest sign his campaign fury has not faded, US President Donald Trump has taken another swing at former presidential candidate Hillary Clinton, retweeting a mock video that shows him hitting her with a golf ball.

The video shows Mr Trump hitting a golf ball that, in the next frame, seemingly strikes Mrs Clinton in the back before she stumbles and falls down while boarding a plane.

It appears to be a doctored version of news footage from 2011 that shows the then-secretary of state falling after climbing the aeroplane stairs.

Mr Trump retweeted the brief video on his official Twitter account early on Sunday (local time).

A spokesman for Mrs Clinton declined to comment.

The White House issued no immediate comment, and Trump aides have said in the past that his tweets "speak for themselves".

Back in July, Mr Trump vented his rage against the media by posting someone else's doctored anti-CNN video that showed Mr Trump pummelling a man in a business suit — the man's face obscured by the CNN logo — outside a wrestling ring.

This time, Mr Trump has retweeted a user with the Twitter name "CNN sucks".

Tensions flare over Clinton memoir

Mr Trump has stepped up his criticism of Mrs Clinton since the Democratic presidential nominee re-emerged in the spotlight to promote her new book about the 2016 campaign.

She is unsparing in her assessment of Mr Trump, calling him "a clear and present danger to the country and the world".

Mr Trump often cites his electoral vote victory as evidence of campaign prowess and popularity with Americans.

He is quick to challenge or criticise anyone or anything that might undercut that premise.

Mr Trump has established a commission to investigate his unsubstantiated claims that millions of people voted illegally in 2016, when Mrs Clinton won the popular vote by nearly 2.9 million votes.

"It is distressing though to have a President that, frankly, will tweet and retweet things as juvenile as that," US representative Adam Schiff of California said in a televised interview.

"It doesn't help, I think, in terms of his stature. It doesn't help in terms of the stature of our whole country."

Mrs Clinton's book assigns blame for her presidential loss on several factors, including interference from Russian hackers, accusations levelled at her by former FBI director James Comey and even her gender.

The White House has criticised the book, with spokeswoman Sarah Huckabee Sanders calling it "sad" that the last chapter of Mrs Clinton's public life will be defined by selling books with "false and reckless attacks".

In a pair of tweets last week, Mr Trump took direct aim at Mrs Clinton.

"Crooked Hillary Clinton blames everybody (and every thing) but herself for her election loss. She lost the debates and lost her direction!" Mr Trump wrote.

Referring to Mrs Clinton's past description of some Trump supporters, he later tweeted: "The 'deplorables' came back to haunt Hillary. They expressed their feelings loud and clear. She spent big money but, in the end, had no game!"
