Milo Yiannopoulos, a British provocateur who promoted far-right conspiracies and racism in the United States, was deported to Britain on Friday, according to a statement from the Department of Homeland Security.
Mr. Yiannopoulos, an early supporter of Donald J. Trump who later dabbled in helping the rapper formerly known as Kanye West explore a run for president, had been arrested on Thursday by Immigration and Customs Enforcement officers at Louis Armstrong New Orleans International Airport.
D.H.S. said in a statement that Mr. Yiannopoulos had entered the country legally in 2019 but overstayed his visa. He was issued a final deportation order by an immigration judge in July after he failed to show up for his hearing, according to the department.
A mug shot of Mr. Yiannopoulos was released online by D.H.S. with a warning that other immigrants “take control of their departure” by self-deporting.
The Trump administration is increasingly targeting foreign citizens at American airports. Immigration agents have whisked away people at check-in counters and arrival gates based on information airlines provide to the Transportation Security Administration.
Mr. Yiannopoulos did not respond to messages seeking comment. He had lived in the United States for more than a decade, joining the staff of Breitbart News on a nonimmigrant visa reserved for people with “extraordinary ability.”
He has frequently tested the limits of his provocations with incendiary remarks about Islam, feminism and immigrants.
Mr. Yiannopoulos has also reveled in Mr. Trump’s mass deportation campaign. Last year on social media he called for “on the spot deportation” for those who couldn’t prove they were in the country legally.
He was deported a decade after becoming an early and prominent supporter of Mr. Trump’s first run for office.
Once an emerging star in the new conservative culture shaped by Mr. Trump, Mr. Yiannopoulos fell from right-wing grace in 2017, after he condoned sexual relations with boys as young as 13 while laughing off pedophilia by Roman Catholic priests. Those comments appeared to cost him a book deal, his job at Breitbart and an invitation to speak at the Conservative Political Action Conference, or CPAC.
In 2022, Mr. Yiannopoulos claimed credit for arranging a dinner that included Mr. Trump, Mr. West and the white supremacist Nick Fuentes. Two years later, Mr. Yiannopoulos joined an exploratory presidential campaign for Mr. West, who by then was known as Ye and embroiled in controversies over antisemitic remarks that included praise for Adolf Hitler.
Mr. Yiannopoulos also made headlines that year for serving as an intern for Representative Marjorie Taylor Greene, a Republican who resigned after falling out with Mr. Trump.
Laura Loomer, the right-wing activist and associate of Mr. Trump’s, had been calling since late 2024 for Mr. Yiannopoulos, a former ally, to be deported. Ms. Loomer has now claimed credit for Mr. Yiannopoulos’s arrest.
“Loomered!” she said, using a term she applies to the collection of people who have been fired, deported or otherwise reprimanded by the Trump administration after her calls for action. “I have been saying this should happen for a long time and now it did.”
Mr. Yiannopoulos was banned from the site then known as Twitter in 2016 for leading a harassment campaign against a Black actress, but reinstated in 2022 after Elon Musk purchased the platform and later renamed it X.
Mr. Yiannopoulos posts almost daily on the platform. He has yet to publicly comment on his deportation.
