Hillary Clinton takes a swing at Donald Trump over time spent on the golf course

Hillary Clinton has taken a swing at Donald Trump, by retweeting a data project that claims he spent 25 hours playing golf during his first month in office.

The former Democratic presidential nominee shared a graph with her millions of Twitter followers that claimed to show that Mr Trump had spent more than four times longer playing golf than receiving intelligence briefings.

It was estimated by the Washington Post that during Mr Trump's first full month in office after his inauguration on January 20 (a total of 744 hours) he had spent: 

• 25 hours - playing golf

• 6 hours - receiving intelligence briefings

• 6 hours - signing bills and executive orders

• 21 hours - on foreign relations (meetings and phone calls with foreign leaders)

• 4 hours - taking news news conferences

The data is based on pool reports and the time between when the media was told to arrive in the morning until the media was dismissed in the evening.

The newspaper itself admitted that the metrics used were "imprecise".

Mr Trump played a round with Rory McIlroy, the Northern Irish golfing superstar, at his Trump International course in south Florida on Sunday.

The four-time major winner said of Mr Trump: "He probably shot around 80. He’s a decent player for a guy in his seventies!"

However, there was confusion when a White House spokesman said Mr Trump had only "played a couple of holes" on Saturday and Sunday, whereas McIlroy said their group had played a full 18.

He also played a round with Shinzo Abe, the Japanese prime minister, earlier this month.

Mr Trump was a frequent critic of the amount of time his predecessor, Barack Obama, spent on the golf course:
