Washington Nationals fans expressed outraged after U.S. President Donald Trump embraced catcher Kurt Suzuki who wore a "Make America Great Again" baseball hat during a ceremony to welcome the 2019 World Series Champions at the White House in Washington, DC, on Nov. 4, 2019.

Hundreds of Washington Nationals fans gathered on the South Lawn of the White House on Monday to celebrate their team's World Series win over the Houston Astros in 7 games.

"I love you all, I love you all. Thank you," Suzuki said, as the crowd roared.

"I didn't know that was going to happen," Trump said after Suzuki put on the red cap that is considered a racist symbol of white nationalists.

One player, Sean Doolittle, declined the invite to attend the ceremony at the White House because his wife's parents are lesbians.

"There's a lot of things, policies that I disagree with, but at the end of the day, it has more to do with the divisive rhetoric and the enabling of conspiracy theories and widening the divide in this country," Doolittle told The Washington Post. A handful of other players also didn't attend.

President Trump was booed when he and his wife Melania Trump attended game 5 of the World Series in D.C. Those same fans took to Twitter to complain about young Suzuki's patriotism.

One fan tweeted: "Did Trump think Kurt Suzuki was someone else’s wife in this picture???"

Another Twitter user wrote: "People keep comparing that pic of Trump and Kurt Suzuki to Titanic, but his administration already hit the iceberg awhile ago."
