TV talk show host Ellen DeGeneres, who was awarded the 2016 Presidential Medal of Freedom — the highest civilian honour in the United States, conducted a “mannequin challenge”, a video that features people frozen in place, with other recipients.

President Barack Obama awarded the medals to 21 key figures at a star-studded ceremony at the White House on Tuesday.

Obama presented the prestigious medal to Microsoft co-founder Bill Gates and his wife Melinda for philanthropic work, former basketball players Michael Jordan and Kareem Abdul-Jabbar and actors Tom Hanks, Robert De Niro and Robert Redford.

“It’s useful when you think about this incredible collection of people to realise that this is what makes us the greatest nation on earth,” Obama said.

The medal is given annually to those who have made outstanding contributions to the national interests of the United States, to security, world peace, cultural or other significant public or private endeavours.

Other recipients this year were rock star Bruce Springsteen, soul singer Diana Ross, Native American community leader Elouise Cobell and Nasa moon landing computer scientist Margaret H. Hamilton.

“Everybody on this stage has touched me in a very powerful personal way,” Obama said. “It’s useful when you think about this incredible collection of people to realise that this is what makes us the greatest nation on earth.

“Not because of what we are, not because of our differences, but because in our difference we find something common to share.”

While speaking on the accomplishments of DeGeneres, Obama lauded the comedian’s courage for coming out as gay.

“What an incredible burden that was to bear, to risk her career like that,” he said. “People don’t do that very often, and then to have the hopes of millions on your shoulders.”

As is his style Obama broke up the weightier moments during the ceremony with a humorous touch.

“But it’s like Ellen says: ‘We all want a tortilla chip that can support the weight of guacamole.’ Which really makes no sense to me, but I thought that would break the mood because I was getting kind of choked up.”

Obama also praised actor De Niro’s many iconic roles.

“A Sicilian father turned New York mobster, a mobster who runs a casino, a mobster who needs therapy,” the president read off, drawing laughter from the crowd. “A father-in-law scarier than a mobster, Al Capone, a mobster.”

De Niro has been in the spotlight recently for his candid disapproval of President-elect Donald Trump. The actor hasn’t minced words in his criticism of the Republican, describing him as “a punk”, “a pig”, and “an idiot.”

“I’d like to punch him in the face,” he said before the election
