US President Donald Trump has retweeted a doctored video of himself taking a golf swing and hitting former Democratic presidential rival Hillary Clinton, who then stumbles as she boards a plane.
Ms Clinton had been back on the Republican president's Twitter feed in recent days as she promoted What Happened, her new book about the 2016 presidential campaign, with Mr Trump resuming his campaign attack of "Crooked Hillary".
The video, retweeted by several users, shows Mr Trump on a golf course hitting a ball before seguing to the doctored shot of a golf ball hitting then-secretary of state Ms Clinton in the back as she is boarding a plane. The original video of Ms Clinton, from 2011, does not show a golf ball.
"Donald Trump's amazing golf swing #CrookedHillary," the tweet read.
Mr Trump attacked Ms Clinton directly last Wednesday in a pair of Twitter posts.
"Crooked Hillary Clinton blames everybody (and everything) but herself for her election loss. She lost the debates and lost her direction!" he said. "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!"
White House spokeswoman Sarah Sanders said later that day Ms Clinton was pushing "false narratives" in the book, in which she admits personal mistakes during the campaign but takes a harsh look at factors that led to Mr Trump's victory, including alleged interference by Russia on his behalf and former FBI director James Comey's decision to announce that investigators were looking at a new trove of emails related to Ms Clinton.
Ms Clinton, who has been giving a series of interviews promoting the book, responded to Mr Trump's earlier criticism on Twitter by retweeting a suggestion that he read her earlier book, It Takes a Village - a picture book for children.
