The Trump campaign complaint to the Federal Election Commission flags that senior Labour Party staff attended the Democratic convention in Chicago and met Harris’s campaign team, naming Morgan McSweeney, the prime minister’s chief of staff, and Matthew Doyle, Downing Street director of communications.

The British Prime Minister’s Labour Party was formally accused by Donald Trump’s presidential election campaign of breaking U.S. electoral law through “blatant foreign interference” in the race.

Trump, who hasn’t yet addressed the topic, has himself waded into British politics in the past. As President, he endorsed Johnson’s 2019 bid for the Conservative Party leadership and, while weighing into the country’s election campaign months later, said that the then-opposition Labour Party Jeremy Corbyn would be “ so bad ” for Britain.
