In a bid to get Americans to sign up to Obamacare, the President has appeared in a Twitter video with Hollywood actor Bill Murray playing golf in the Oval Office.

After ribbing each other about their support of rival baseball teams the Chicago Cubs and the Chicago White Sox, the pair begin putting golf balls into overturned glasses on the floor.

While Murray succeeds on both occasions, Barack Obama fails, leading the 66-year-old to tell the President to play with American former World Number One golfer Jordan Spieth.

On Mr Obama's second failed attempt to pot the ball, Murray bends down to pick up the ball, but exclaims in pain.

After asking him if he is alright, Mr Obama learns that the Ghostbusters star has not been to see a doctor because he does not have a health insurance.

To which the President responds: "Well Bill, you don't have to go without health insurance because these days - because of the Affordable Care Act anybody can get health insurance, and it doesn't matter if you already have something wrong with you because insurance companies have to take you even if you have a pre-existing condition."

The Ghostbusters star then asks if mental health care is covered as well, to which Mr Obama replies that it is.

The Affordable Care Act, more commonly known as Obamacare is a US healthcare reform law which is Mr Obama's flagship domestic policy brought in during his time in office.

Obamacare seeks to expand and improve access to care and curb spending through regulations and taxes. It is intended to make healthcare more accessible to millions of Americans, including the estimated 15% of the population who do not have it.

Thursday marks the last day Americans can sign up for health care coverage if they want it to start on January 1, 2017.

While campaigning to be president, Donald Trump frequently promised to "repeal and replace Obamacare", yet since finding himself on the way to the Oval Office, Mr Trump has since rowed back on his promises, now saying he is open to keeping elements of it.

Many Republicans oppose Obamacare as they say it imposes too many costs on businesses (companies with more than 50 employees must offer health insurance under the law), with many describing it as a "job killer" and also decried it as an unwarranted intrusion into the affairs of private businesses and individuals.
