Trump is still expected to attend the game - his first appearance at an Major League Baseball contest since being elected in 2016. Hours earlier, he had announced that US forces had assaulted the hiding place of Islamic State leader Abu Bakr al-Baghdadi, who was killed in the raid in northeast Syria.
This was the first time Donald Trump was attending a Major League Baseball game since he took office in January of 2017.
Jose Andrés, a prominent local restaurant owner and humanitarian, threw out the first pitch to a roaring, sustained ovation.
Trump was introduced to the crowd after the third inning, during the Nationals "Salute to Veterans".
Andres also canceled plans to run a restaurant in Trump's Washington hotel because of Trump's disparaging comments about Mexicans, which led to a legal settlement. "He would arrive at Game 5 sometime after the game began so it wouldn't interfere with fans getting into the stadium".
The Astros won the fourth game, 8-1, to tie the Series at 2-2.

He said the new injury appears to be unrelated to that issue, which was more a problem with the lower region of the back. Once again, though, Houston won the next game to claim the series. "There was nobody better to have on the mound".
The president, 73, and the first lady, 49, received their share of ire from ballpark goers, with many in the crowd erupting into a roaring sea of "boos" as the couple's image flashed on the big screen.
A longtime New York Yankees fan who was spotted regularly at games in the Bronx, he was also a high school player with enough talent that, he has said, he drew the attention of big-league scouts.
It's rare to see Trump out in public in Washington, a Democratic stronghold in which just 4 percent of the residents voted for Trump in the 2016 general election. That being said, it's unfortunate that, if only for a couple of minutes, the World Series had to be turned into a political standoff between Trump supporters and Trump opponents. So just why in the hell he thought he could get away with not only going to a World Series baseball game, let alone have himself splashed across the giant stadium screen, will remain a mystery for a long, long time.
