That was likely not the reaction President Donald Trump expected when he attended Sunday night’s World Series game in Washington.

Audible boos rained down on the president after the third inning, when the outfield video screen showed Trump sitting in a luxury box. Immediately before, the crowd had been cheering video of U.S. servicemembers. The jeers were followed with a chant of “Lock him up!”

Other Trump critics displayed signs behind home plate — directly in line with TV cameras — that read “Veterans for impeachment.”

Trump, along with first lady Melania Trump and a group of lawmakers including Sen. Lindsey Graham, attended Game 5 of the World Series, pitting the Washington Nationals against the Houston Astros.

It should have been a triumphant moment for Trump, who earlier Sunday announced the death of Islamic State leader Abu Bakr al-Baghdadi in a U.S. military raid. Some analysts said the raid could be a political boost for Trump, who is embattled in impeachment proceedings.

It was the first baseball game Trump has attended as president, though he did not throw out the first pitch, which Major League Baseball Commissioner Rob Manfred said Trump didn’t want to do anyway. “His view was that in order to make the fan experience as positive as possible, he would arrive at Game 5 sometime after the game began, so that wouldn’t interfere with fans getting into the stadium,” Manfred said, according to the Associated Press.

Instead, that honor that went to outspoken Trump critic and acclaimed chef Jose Andrés.

Nationals fans had few other reasons to make noise Sunday — the Astros jumped out to a 2-0 lead in the second inning and cruised to a 7-1 victory, their third straight win as they took a 3-2 series lead. The series now returns to Houston, where the Astros could clinch their second championship in three years on Tuesday.
