The investigators are also looking for potential obstruction of justice in Mr Comey's firing, sources familiar with the matter told CNN.
US President Donald Trump's son-in-law and adviser Jared Kushner handed over documents related to the Russian Federation probe to Special Counsel Robert Mueller's team, media reported. That fact could add to Trump's reported aggravation with his son-in-law.
In a call Tuesday with former White House Chief strategist Stephen Bannon, Trump laid the blame for the expanding scandal surrounding Mueller's probe into Russian election interference squarely on Kushner's shoulders, Nunberg told Vanity Fair.
Kushner, 36, who is married to President Trump's daughter Ivanka, voluntarily turned over the documents - which had been previously presented to congressional investigators - to Mueller's team "in recent weeks".
Former Trump campaign chief Paul Manafort and his business associate Rick Gates surrendered to the Federal Bureau of Investigation this week over charges stemming from an Federal Bureau of Investigation probe into alleged Russian Federation meddling in the 2016 USA presidential election. He was also among three top Trump campaign officials who attended an infamous June 2016 meeting at Trump Tower with a Kremlin-backed lawyer. His attorneys have repeatedly said he will cooperate with Mr Mueller's investigators.

But for Halloween on Tuesday , the city is slated to be drier and brighter, with daytime temperatures in the upper 50s. Smaller creeks and streams along with poor drainage areas and low-lying areas will be the most prone to flooding.
The White House didn't respond to Vanity Fair's request for comment. During the meeting, the lawyer reportedly lobbied Donald Trump, Jr., Kushner, and then-campaign chair Paul Manafort on overturning the Magnitsky Act. He would be among a list of people the investigators would be asking about, the source said.
The network based its report on "sources close to the White House". "The walls are closing in", one senior Republican close to the White House told the "New York Post". Both pleaded not guilty. The Russia investigation is such a party matter, and this means that any former government official who participated in deliberations or a decision about the Russia investigation-for example the White House decision to fire FBI Director James Comey because of the Russia investigation-may not represent back to the government on behalf of anyone else with intent to influence a government decision about the Russia investigation.
Manafort laundered over $18 million, according to the indictment.
Kushner was also under scrutiny for meetings with Russia's ambassador to the US and a Russian banker, and for failing to list hundreds of meetings with foreign contacts on his security clearance forms, which he blamed on an assistant.
