Asked during an appearance on ABC's This Week whether the tweet made him doubt the sincerity of Mr Trjmp's outreach to Democrats, Rep. Adam Schiff said it was "distressing" to have a president who "will tweet and re-tweet things as juvenile as that".
One tweet opened with the phrase "Donald Trump's incredible golf swing #CrookedHillary" along with a video of a man in a red hat driving a golf ball that then strikes and knocks down a blond woman as she boards an airplane - implying that the video showed the president assaulting Ms Clinton, the former Democratic nominee whom Mr Trump defeated for the presidency.
The GIF combines real footage of Trump playing golf and Clinton falling over as she walks onto a plane, but the golf ball has been edited into the Clinton video to make it seem as though it had struck her. Clinton has heavily criticised Trump recently while promoting her new book, What Happened, which deals with her 2016 election defeat.
"Donald Trump's unbelievable golf swing #CrookedHillary", the tweet reads.
He said: "Crooked Hillary Clinton blames everybody (and every thing) but herself for her election loss".
"The "deplorables" came back to haunt Hillary.They expressed their feelings loud and clear".
White House spokeswoman Sarah Sanders said later that day that Clinton was pushing "false narratives" in the book.
When pressed on why the president may have retweeted a doctored image showing him physically hurting the former secretary of state, former Trump adviser David Urban stressed that his scandal-prone boss was not necessarily endorsing violence against Clinton.
Donald Trump continued to redefine the bounds of acceptable behavior Sunday morning, launching what would, in any other administration, be a headline-making fusillade of online attacks: mocking North Korea, joking about physically assaulting Hillary Clinton, and sharing other images and memes from presumably unvetted, unidentified supporters on Twitter.
Trump has often retweeted or responded to random Twitter accounts praising him before.
"I have too little distance and too great a stake in it - instead this is my story".
