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.
Well, maybe not. With this season set to conclude with Super Bowl 60 on Sunday, BBC Sport examines Trump's long and complicated relationship with the NFL and why it could be set for another twist.
Lawsuit fails to force league merger
Already a real-estate magnate by that point, Trump viewed owning an American football team as a means of building his brand. After attempting to acquire an NFL franchise, a 37-year-old Trump bought the New Jersey Generals in September 1983.
They were founding members of the USFL, which started in the spring of 1983 so did not clash with the NFL. The new league managed to lure top players from the NFL and the college game.
The Generals improved during their two seasons under Trump but lost in the first round of the play-offs in both 1984 and 1985.
However, Trump had made his intentions clear from the outset. He didn't want the USFL to remain a spring league; he wanted to go directly against the NFL in autumn-winter.
That was not the USFL's original plan but, in August 1984, Trump convinced team owners to vote on switching to an autumn-winter schedule from 1986.
Then, two months, later the USFL filed an anti-trust lawsuit against the NFL - led by Trump. The case went to trial in May 1986, with the USFL arguing the NFL had conspired to monopolise TV contracts, seeking damages worth $1.7bn (£1.25bn).
Trump hoped it would force a league merger and earn him an NFL franchise. He also envisaged a Trump-branded stadium in Manhattan.
The trial lasted 42 days and a jury found the NFL was an 'illegal monopoly'. But it rejected the other charges and the USFL was awarded just $3 as the jury felt most of the USFL's problems were self-inflicted.
The league had built up huge debt and, days after the verdict, it folded.
In a book about the USFL,, external one of the jurors said Trump "came off as arrogant and unlikeable" in court.
Trump and then NFL commissioner Pete Rozelle provided contrasting accounts of a meeting they had in March 1984, during which Rozelle is alleged to have told Trump, external "as long as I or any of my heirs are involved in the NFL, you will never be a franchise owner in the league".
Did failed Bills bid lead to presidential run?
Trump had already attempted to buy the Baltimore Colts, before the NFL franchise relocated to Indianapolis in 1984.
He then turned down the chance to buy the Dallas Cowboys for $50m in 1984 and bought the Generals instead for $9m.
"I feel sorry for the poor guy who is going to buy the Dallas Cowboys," he told the New York Times.
Jerry Jones became the Cowboys' owner in 1989. 'America's Team' won three Super Bowls in the '90s and are now the world's most valuable sports team at $10.1bn (£7.5bn)., external
After the USFL's demise, Trump pulled out of discussions in 1988 to buy the New England Patriots, who have won six Super Bowls under current owner Robert Kraft.
Trump focused on other enterprises, becoming a reality TV star on The Apprentice, until the Buffalo Bills were put up for sale in 2014.
Trump claims he bid $1bn in cash but Terry Pegula, who already owned the NHL's Buffalo Sabres, ultimately bought the Bills for $1.4bn.
That bidding process was mentioned during the fraud trial that ruled against Trump - who had denied all accusations - in 2024, before his $500m (£372m) penalty was overturned last week.
His former lawyer Michael Cohen used it as an example of how he would inflate Trump's assets, in that case claiming a net worth of $8bn in a bid to secure a loan to buy the Bills.
Documents also showed Trump declined to provide financial statements to the Bills' bankers - one of whom testified that, instead, Trump "gave us handouts of the Forbes list of the top-paid entertainers".
ESPN analyst Stephen A. Smith has repeatedly claimed that before Pegula's takeover was approved by NFL team owners in October 2014, he received a call from Trump in which he said: "If they screw me over, I am going to show them. I'm going to get them all back. I'm going to run for president."
Eight months later, Trump announced he was doing just that. He later said: "If I bought that team, I wouldn't be doing what I'm doing.''
Trump and the anthem debate
It was during Trump's first presidential run that NFL quarterback Colin Kaepernick began taking the knee during America's national anthem, to protest against racial injustice and police brutality in the US.
Many NFL players followed suit and Trump was a vocal critic, before and after he was elected in November 2016.
During a rally in September 2017, Trump urged fans to boycott games and NFL team owners to sack any players who did not stand for the anthem. He also called for the league to change its rules, regarding both the protests and the game itself.
The following day NFL commissioner Goodell issued a statement, in which he said: "Divisive comments like these demonstrate an unfortunate lack of respect for the NFL."
Patriots owner Kraft told BBC Sport that Trump's comments on the anthem protests were "inflammatory and inappropriate". In a meeting between players and owners in October 2017,, external Kraft added: "We have a president who will use that as fodder to do his mission, that I don't feel is in the best interests of America".
After a team owners' meeting in the same month, the Jacksonville Jaguars owner Shahid Khan told USA Today, external that Trump was "trying to soil a league or a brand that he's jealous of".
Khan added: "He's been elected president, where maybe a great goal he had in life to own an NFL team is not very likely, so to make it tougher, or to hurt the league, it's very calculated."
Trump said he "would love" to see Kaepernick return to the NFL as it continued to struggle with the anthem issue.
In May 2018, the NFL introduced a new policy giving players the option to stand or stay in the locker room but, in the wake of George Floyd's death, Goodell admitted the NFL was wrong and encouraged players to peacefully protest.
Smith has said Trump "hijacked the narrative" over Kaepernick "for his own benefit", while his ESPN colleague Adam Schefter said Trump was "waging his own little vendetta against the NFL".
