A Bugatti, a first lady and the fake stories aimed at Americans ( www.bbc.com )

Another fake which went viral earlier this year was more directly aimed at American politics.

It was published on a website called The Houston Post – one of dozens of sites with American-sounding names which are in reality run from Moscow - and alleged that the FBI illegally wiretapped Donald Trump’s Florida resort.

It played neatly into Trump’s allegations that the legal system is unfairly stacked against him, that there is a conspiracy to thwart his campaign, and that his opponents are using dirty tricks to undermine him. Mr Trump himself has accused the FBI of snooping on his conversations.

Experts say that the operation is just one part of a much larger ongoing effort, led from Moscow, to spread disinformation during the US election campaign.

While no hard evidence has emerged that these particular fake news websites are run by the Russian state, researchers say the scale and sophistication of the operation is broadly similar to previous Kremlin-backed efforts to spread disinformation in the West.

“Russia will be involved in the US 2024 election, as will others,” said Chris Krebs, who as the director of the US Cybersecurity and Infrastructure Security Agency was responsible for ensuring the integrity of the 2020 presidential election.
