Sep 11, 2025; Bronx, New York, USA; President of the united states Donald Trump is shown on the video board before the singing of god bless america during the seventh inning between the Detroit Tigers and the New York Yankees at Yankee Stadium.

A mock-up of a Truth Social post shows President Donald Trump bashing the hometowns of the two Major League Baseball teams in the World Series, but it is fake.

"No matter who wins I will refuse to invite either baseball team to my ballroom as they are both run by highly inept officials from California and Ontario Canada," the post, shared by a meme account on Instagram and widely shared on social media, read. "I don't host losers. We are actively investigating MLB. This World Series is rigged, probably by the Dems & Mafia."

USA TODAY found no evidence he actually posted this on Truth Social. The same Instagram account that posted it posted several other fictional posts made to look like they came from Trump.

The Los Angeles Dodgers are tied 1-1 in the best-of-seven World Series against the Toronto Blue Jays, with game three coming October 27 in L.A.

However, Trump has a record of criticizing the leaders of California and Canada before. Here is what to know:

Trump ignores Canada prime minister's MLB bet over tariffs

Canadian Prime Minister Mark Carney wanted to bet Trump on the Toronto Blue Jays beating the Los Angeles Dodgers in the World Series, but said he never got a call back.

Instead, Trump upended trade negotiations with Canada after a television ad with the voice of former President Ronald Reagan talking about tariffs. It was paid for by the Ontario provincial government, the province whose leader threatened to cut off energy flow to some U.S. states if Trump moved forward with its tariffs against the northern neighbor. “CANADA CHEATED AND GOT CAUGHT!!!” he wrote on Truth Social on Oct. 23. “They fraudulently took a big buy ad saying that Ronald Reagan did not like Tariffs, when actually he LOVED TARIFFS FOR OUR COUNTRY, AND ITS NATIONAL SECURITY.”

Reagan said in the voiceover from an April 25, 1987 address, which was spliced up for the ad, that he was not a fan of tariffs but had imposed them on certain Japanese imports in response to Japan violating a semiconductor trade agreement. The ad aired during the first two World Series games but Ontario Premier Doug Ford said it would pause Oct. 27.

Trump has also said Canada should be the 51st state, despite rebuke from local leaders.

Trump and Gavin Newsom in a longstanding feud

California Gov. Gavin Newsom has been an outspoken critic of Trump, and in turn, Trump often calls him "Newscum."

Newsom has been at the forefront of a state redistricting standoff prompted by Texas lawmakers' move to redraw the state's congressional map to add more Republican seats. On Aug. 14, Newsom announced the Democratic-leaning state would hold a special election to approve a mid-decade redistricting plan in the hopes of adding some more Democratic seats.

The California governor's office has taken to mimicking Trump's social media style in posts trolling the president and generally poking fun at Republicans online.

Newsom addressed speculation that he would run for the Democratic presidential ticket in 2028 in a "CBS News Sunday Morning" interview that aired Oct. 26, saying he is considering it.
