An ex-aide of Donald Trump has shared more than 120,000 emails said to be from Hunter Biden’s laptop online.
Garrett Ziegler, a former director for trade and manufacturing policy under Mr Trump, uploaded a total of 128,775 emails to a database on his research group called Marco Polo.
The group says it specialises in “exposing corruption and blackmail”.

This comes as Hunter continues to be accused of using his family name to conduct overseas business deals that could compromise his father.
The claims have been heightened by the emergence of a laptop that allegedly belongs to the US President's son.
Mr Trump’s legal team originally leaked some details they claim to be on Hunter’s laptop ahead of the 2020 Presidential election.
Among the content leaked include an email sent by James Gilliar, a business associate of Joe Biden.
The email seemed to suggest a distribution of shares from a venture in China, which included the words “10 held by H for the big guy”.

In the latest alleged leak, a fresh email dated from February 2016 seemingly showed Hunter becoming frustrated with the son of a Mexican billionaire.
The email says: “We have been talking about business deals and partnerships for seven years.
“And I really appreciate you letting me stay at your resort villa…but I have brought every single person you have ever asked me to bring to the f’ing White House and the Vice President’s house and the inauguration and then you go completely silent.
“I don’t hear from you for months. I don’t know what it is that I did but I‘d like to know why I’ve delivered on every single thing you’ve ever asked - and you make me feel like I’ve done something to offend you.”
But the Marco Polo site has now included a disclaimer about the content which reads: "Having seen the lengths that the FBI and other entities in the apparatus have gone to harass citizens who expose corruption.
“Marco Polo testifies that the contents of the Biden Laptop were abandoned property. We do not condone, encourage, intend, or have any knowledge that any other person will or may use the information herein for any unlawful purpose.
“Marco Polo’s motive is to see justice delivered, to all criminals, by those whose responsibility it is to carry out that duty.”
Hunter has always denies any allegation of wrongdoing.
