President Donald Trump said Saturday that he plans to sign an executive order protecting the broadcast slot for the Army-Navy football game.

Trump's announcement on Truth Social comes amid a push to expand the NCAA College Football Playoff, which could potentially affect the Army-Navy game’s traditional time slot.

"The Army-Navy Game is one of our Greatest American Traditions — Unmatched Patriotism, Courage, and Honor!" Trump wrote. "This incredible Tradition is now at risk of being pushed aside by more College Playoff Games, and Big TV Money. NOT ANYMORE!"

The president said his executive order will secure an exclusive four-hour broadcast window in December for the event that cannot be challenged by another postseason football game.

"Under my Administration, the second Saturday in December belongs to Army-Navy, and ONLY Army-Navy!" Trump said. "I will soon sign a Historic Executive Order securing an EXCLUSIVE 4 hour Broadcast window, so this National Event stands above Commercial Postseason Games. No other Game or Team can violate this Time Slot!!!"

Trump praised the rivalry, adding that "on the battlefield they are America’s unstoppable Patriots, defending our Country with tremendous Strength and Heart."

"We must protect the Tradition, and the Players, who protect us," he added. "Please let this serve as Notice to ALL Television Networks, Stations, and Outlets."

Trump attended the 126th installment of the rivalry game at M&T Bank Stadium in Baltimore on Dec. 13, his seventh appearance at the game. The Navy Midshipmen captured the Commander-in-Chief's Trophy with a 17-16 victory over Army.

The president said he will also attend the College Football Playoff championship Monday in Miami, alongside Secretary of State Marco Rubio.

The Seattle Seahawks punched their ticket to the NFC Championship game with a 41-6 stomping of their division rival San Francisco 49ers in Saturday's divisional round playoff game.

Seahawks quarterback Sam Darnold took the field amid doubt that he would be able to play due to an oblique injury. Darnold threw for 124 yards and one touchdown amid the concern for his first career playoff win, while Seattle's running game took care of most of the offense. 

Running back Kenneth Walker III had 116 rushing yards with three touchdowns.

San Francisco quarterback Brock Purdy had 140 passing yards with no touchdowns and one interception, as he was never able to get the 49ers offense into the end zone, only managing two field goal drives. 

Seattle will now await the winner of Sunday's other NFC divisional round game between the Chicago Bears and Los Angeles Rams to see who their opponent will be.

Seattle hasn't been back to the NFC Championship since 2014, when they sought to defend their Super Bowl title, beating Aaron Rodgers in the Green Bay Packers at home in that game, but then falling short to Tom Brady and the New England Patriots in the Super Bowl.

Darnold will be looking to put an exclamation point on a dramatic resurgence after a slow start to his pro career with the New York Jets. Darnold has also found some big-game redemption after faltering for the Minnesota Vikings late in the season last year.
