Trump attended part of Game 5 at Nationals Park in Washington and was greeted with both cheers and boos. When the boos began as Trump's image flashed on the ballpark's giant video screen, the president seemed momentarily taken aback. He mouthed something to his wife, Melania Trump, while gamely trying to clap along.
But his smile froze and then faded as the boos continued and some in the crowd launched into a brief chant of "Lock him up," a version of the phrase chanted against Hillary Clinton at dozens of Trump rallies during the 2016 campaign.
The Washington Post reported that relief pitcher Sean Doolittle confirmed he does not plan to participate in the White House visit . Doolittle and his wife, Eireann Dolan, have worked with Syrian refugees and military veterans, as well as supporting gay rights. He has not specifically spoken out against Trump.
