Veterans for Impeachment staked out a high visibility site for their message at Game 5 of the World Series between the Washington Nationals and the Houston Astros: right behind home plate.

A blue sign, reading “Veterans for Impeachment,” managed to grab national audience views when the cameras trained on batters at Nationals Park. The sign also appeared on the Jumbotron in the stadium where Donald Trump watched the game. When the president and first lady appeared on the Jumbotron as well, the crowd booed him and chanted “Lock him up.”
