Donald Trump retweets meme of him 'eclipsing' former US president Barack Obama

US President Donald Trump has retweeted a quadruple photo spread of him slowly eclipsing the former president Barack Obama.

The series starts with a photo that shows a glimpse of Mr Trump, who is in colour in the frame, along with a black-and-white image of Mr Obama.

Mr Trump gradually commands more of the frame in the next two photos until the fourth and final one shows a smiling Mr Trump and no Mr Obama.

Mr Trump retweeted the series, titled "The Best Eclipse Ever!" from Twitter user, @JerryTravone.

It comes three days after North America was treated to a solar eclipse.

Mr Travone describes himself on Twitter as a YouTube actor, political junkie and "Proud Trump supporter".

Recently Mr Trump delivered one speech in which he tore into the media and members of his own party, and a second in which he called for national unity and love, all within a 24-hour span.

The about-face seemed to reflect the president's real-time internal debate between calls for moderation and his inclination to let loose.

On Wednesday, the president spoke in measured tones and stuck to his prepared remarks as he praised veterans at an American Legion conference in Nevada as examples for a nation yearning to set aside its differences.

The night before, the president cut loose in Arizona, defying instructions from his aides to stick to the script and angrily renewing his fight with the press.
