US media outlet The Federalist reports the Department of Justice has confirmed the FBI is still investigating Hunter Biden and his associates over possible money-laundering offences.
Former Biden business associate Tony Bobulinski claimed he was interviewed by the FBI for five hours in relation to the ongoing investigation.
Mr Bobulinski argued Democratic presidential nominee Joe Biden had been lying about his involvement in Hunter Biden’s foreign business ventures.
The Biden campaign has repeatedly claimed their candidate did not involve himself in his son’s, nor any other member of his family’s, overseas business dealings.
The Trump campaign seized on the story, published on Thursday night, local time.
“Joe Biden has not denied that he met with Tony Bobulinski,” Trump campaign spokesman Tim Murtaugh said.
“He says that Joe Biden is flat out lying when Biden repeatedly said he never spoke with his family members about their foreign business dealings.”
