"We will be following up with subpoenas, and those subpoenas will be created to maximise our chance of getting the information that we need".
One-time advisor of USA president-elect Donald Trump Carter Page addresses the audience during a presentation in Moscow, Russia, December 12, 2016.
Director of National Intelligence Dan Coats on Tuesday refused to address - but did not deny - reports that President Donald Trump asked him to push back against allegations the Trump campaign colluded with Russian Federation, while a former CIA chief testified he was aware of "interactions" between the campaign and Moscow.
"We are still pursuing vigorously, will have more to announce later today in terms of next steps", he said.
Trump associates Paul Manafort and Roger Stone have provided the committee with information, while former campaign adviser Carter Page has not.
He declined to comment specifically on what financial information the committee was obtaining, but speaking in general terms, he noted that one tactic Russians use to influence foreign nationals is financial entanglement.
United States intelligence agencies concluded in January that Russian Federation tried to tilt the November presidential election campaign in Republican Donald Trump's favour, including hacking into and leaking emails of senior Democrats.
President Donald Trump has predicted the investigations won't find collusion, and his efforts to cast doubt and curb the probes have led to the appointment of a special counsel at the Justice Department. He said he was concerned over the number of contacts between Russian officials and Trump campaign operatives.
The leaders of the Senate Intelligence Committee said Tuesday that they were sending subpoenas to Flynn's businesses, the Flynn Intel LLC and Flynn Intel Inc., seeking documents related to dealings with Russian Federation before the election.
In fact, a trip Flynn made to Moscow in December 2015, where he attended a gala dinner and sat next to Russian President Vladimir Putin, was paid for by Russia Today, which U.S. officials consider a state-run propaganda arm, according to documents previously released by the House Oversight Committee.
The threat stemmed from a claim Trump made in a May 9 letter firing FBI Director Comey that he was informed by Comey "on three separate occasions, that I am not under investigation".
He added that the whole debacle is a "witch hunt" and described calls for impeachment by the Democrats as "ridiculous".
"For the evidence to get to the point where you even talk about impeachment, the Republican members would have to think the President's conduct is so serious where it disqualifies him for further service", he said.
He says the Russian intelligence official denied that Russia was meddling, but said he would raise the issue with Russian President Vladimir Putin.
