United States Vice President Mike Pence left Sunday's game between the San Francisco 49ers and Indianapolis Colts at Lucas Oil Stadium after several San Francisco players knelt during the national anthem.
The relationship between the NFL and White House has been strained after President Donald Trump said during a speech in September that any NFL players who protested during the anthem should be kicked off the field or fired.
NFL players who chose to demonstrate during the anthem before Trump's controversial remarks maintained that they were protesting police brutality and racial discrimination and weren't disrespecting the flag or military.
