Trump accuses congresswoman of marrying her brother

US President Donald Trump has accused a member of Congress and frequent critic of his of marrying her own brother.

In a speech given in Florida, Trump repeated a long-disproven myth about Minnesota Representative Ilhan Omar.

"I believe she married her brother, which is totally illegal," Trump said.

Donald Trump has pulled troops out of Germany in response to criticism from Chancellor Friedrich Merz.

"Although, it's a lovely couple, actually, but it's a little bit on the illegal side."

Trump then pretended to be speaking as the couple.

"'Darling, I love you very much.' 'Goodnight, brother. Let's go to bed'," he said.

"Isn't she despicable."

Omar has denied the rumour of her marrying her brother since it began circulating on the internet in 2016.

The rumours appeared to accuse Omar's then-husband of being related to her, which was not true.

She did not mince her words when responding to Trump's comments today.

"This unhinged rant would solicit anger if it wasn't coming from a criminal, who has 34 felony convictions, held accountable for rape and accused of being a pedo," she wrote on X.

Democratic Congresswoman Ilhan Omar.

"I still don't know how anyone would willingly humiliate themselves like this but here we are. 

"(By the way), the pedophile protection party should find new material for their deflection."

Omar has represented Minneapolis in Congress since 2019.

As one of the most progressive politicians in Washington, she has frequently been the focus of Trump's ire.

"She comes here from Somalia and she tells us how to run the United States of America," he said.

"She says 'the constitution gives me certain rights and I demand I be given those rights'."

"Get the hell out. What a phony."

Ilhan Omar was welcomed to her hometown of Minneapolis by a crowd of supporters.

Omar was born in Somalia before moving to a refugee camp in Kenya as a child. 

They arrived in the US in 1995 when she was 12 or 13. Five years later she became a US citizen.

When Omar was allegedly assaulted at an event in January, Trump said she probably set it up herself.

Omar was sprayed with a foul-smelling brown substance while speaking in Minneapolis.

"She probably had herself sprayed, knowing her," Trump said the next day.

In the same speech Trump said it was "treasonous" to suggest the US was not winning the war with Iran.

"We get the radical left to say, 'We're not winning, we're not winning.' They don't have any military left. It's unbelievable," the president said.

"It's actually, it's actually, I believe it's treasonous, okay. You want to know the truth – it's treasonous."
