Fans gathered Sunday night in Nationals Park to watch a World Series showdown between the Washington Nationals and the Houston Astros, politics aside. That game however, quickly turned political when President Trump was recognized for his attendance on the stadium’s jumbotron. Fans quickly erupted in an audible “boo” followed by chants of “lock him up.”

The owners of the Washington Nationals, the Lerner family had previously asked not to sit by the President ahead of Sunday’s game, according to WUSA9. A representative from the family told the news channel that the family requested that the MLB not put them in an “awkward” position to turn down a request to sit in the President’s section.

Earlier in the day, President Trump made a pivotal announcement that U.S. Special Operations Forces had successfully killed the ruthless Islamic State terrorist leader Abu Bakr al-Baghdadi in northwestern Syria. The operation was at Pres. Trump’s direction. It wasn’t enough for Nationals fans.

Sunday’s game was the President’s first appearance at a Major League Baseball game since taking office. Breaking a longstanding tradition, Pres. Trump decided not to throw out the first pitch.
