President Donald Trump was greeted with a chorus of boos and chants of "Lock him up!" along with some cheers on Sunday night as he was introduced at Nationals Park in Washington, D.C., during the team's third World Series home game against the Houston Astros.
Trump, who was there with first lady Melania Trump, stood smiling and clapping throughout.

The announcement afforded the president a political win as he faces an intensifying impeachment inquiry led by House Democrats over his dealings with Ukraine. Democrats on the House Foreign Affairs, Intelligence and Oversight committees are looking into whether Trump abused his powers by withholding $250 million in military aid to Ukraine in exchange for an investigation of former Vice President Joe Biden and his son that would benefit the president politically.
The chants against the president harked back to campaign rallies in 2016 during which fans of Trump would often break into chants of "Lock her up!" in reference to Hillary Clinton.
