The FBI is delving deep into the issue of whether the Russian government's activity meddled, and potentially influenced, the outcome of the recent US elections.
While these investigations were known to be taking place a report on Reuters has shed more specific information on the focus of the investigations and information being gathered.
Most notable it says that an FBI office in Pittsburgh is focusing on breach of the Democratic National Committee's computer systems, which led to major leaks of communications between officials in the organisation, undermining support for candidate Hillary Clinton.
A second investigation in the FBI's San Francisco office is trying to find out the identity of someone who posted emails stolen from Clinton campaign manager John Podesta's who went by the online moniker "Guccifer 2".
Counterintelligence agents and foreign spy agencies are also said to be helping by supplying additional information that they have gathered relevant to the case.
A third investigation is also underway within the FBI focusing on payments believed to have been made from Russia to shell companies that appear to have links to associates of president Donald Trump.
In response to the claims the White House said it had no specific comment and referred instead to comments by Trump during his campaign: "As far as hacking, I think it was Russia, but I think we also get hacked by other countries and other people."
The investigations come amid mounting pressure on the lax security Trump is using while in office, which includes using an old insecure Android smartphone for government business and his staff using their phone lights to illuminate top secrete information.
