The NFL season has been rocked by controversy as players have protested police violence and racial injustice by kneeling or sitting during the anthem, raising the ire of many on the right, including Trump.

Though the protests were started in 2016 by current free agent Colin Kaepernick, Trump fanned the flames in September when he said the league should fire the protesters.

His call led to a wave of player protests across the league, as well as heightened tensions between players and league representatives.

The protests have become one of the most contentious social issues of Trump's presidency, fueling speculation about whether players would kneel during the Super Bowl, the league's annual championship and arguably the biggest American television event of the year.

Trump hosted a Super Bowl watch party at his golf course in West Palm Beach, Fla., before returning to Washington, D.C. on Sunday.
