Washington (CNN) President Donald Trump welcomed the newest Major League Baseball World Series champs, the Washington Nationals, to a celebration at the White House Monday afternoon.

"For the first time in nearly 100 years, our nation's capital is celebrating a World Series victory," Trump said during a celebration from the South Portico of the White House. "The last time Washington, DC, was home to the World Series champs the president was a man named Calvin Coolidge."

A few Nationals players were absent from the celebration, according to a list of anticipated attendees provided by the White House. Those not listed in attendance included Sean Doolittle, Anthony Rendon, Victor Robles, Michael Taylor, Joe Ross, Wander Suero, Javy Guerra and Wilmer Difo.

Doolittle, who's been outspoken in his support for immigrants and the LGBTQ community, said he wouldn't go to the White House because of Trump's rhetoric. He told The Washington Post that he has a brother-in-law who's autistic, and that he remains offended by Trump's mocking of a disabled reporter during the 2016 presidential campaign.

The other baseball players have not publicly disclosed why they did not attend the event.
