NFL commissioner Roger Goodell joined Donald Trump in the Oval Office in May
American football fans never thought they would see the day - the head of the National Football League standing shoulder to shoulder with Donald Trump in the Oval Office.
Trump has frequently traded blows with the NFL since he first became US president in 2017, but he and America's most popular sports league have been sparring partners for more than 40 years.
Trump's 'feud' with the NFL has involved him testifying against the league and failing, on multiple occasions, to buy a team. It may even have propelled him to the presidency.
When NFL commissioner Roger Goodell joined Trump in May to announce the NFL Draft would be coming to Washington DC for the first time, it seemed Trump had finally made friends with arguably his oldest foe.
