SUNDAY TIMES WEB DESK: The investigation — a dual counterintelligence and criminal probe — was launched after the president fired FBI director James Comey in May 2017, the Times said, citing anonymous sources.
The counterintelligence aspect consisted of determining whether Trump was knowingly or unknowingly working for Moscow and whether he was a threat to national security.
It added the criminal portion related to Trump’s firing of Comey.
The FBI investigation was soon folded into Robert Mueller’s inquiry into Russian interference in the 2016 vote and possible collusion between his campaign and Moscow, it said, adding that it was unclear if the counterintelligence aspect was still being pursued.
The Times said that the FBI had been suspicious of Trump’s ties to Russia during the 2016 campaign.
But it held off on opening an investigation until the president sacked Comey, who refused to swear his allegiance and roll back the nascent Russia investigation, which is now being spearheaded by Mueller.
