"In fact, he has already charged a leading law firm in Washington, D.C.to send a certified letter to Senator Graham to that point - that he has no connections to Russian Federation". "He has no business in Russian Federation".
During a White House press briefing Tuesday, press secretary Sean Spicer said the administration would welcome any probe conducted by Graham.
The FBI as well as the US Senate and House intelligence committees have been investigating Russia's alleged meddling in the 2016 US presidential election and any possible ties between Trump's associates and Moscow.
Although Graham admitted that he had no evidence of improper business links between Trump and Russian Federation, he said he was interested in the matter and would like to look into it. Clapper said he could not comment because the issue could be a subject of an ongoing investigation.
Former Director of National Intelligence James Clapper also testified, however, and told the Senate Judiciary subcommittee that he was not aware of any actual evidence that proved collusion between Russian Federation and the Trump campaign.
"The problem is, there are inconsistencies", said Graham.
"This is nothing new here", he told reporters at the Capitol. He also said he didn't know whether it was appropriate for Trump to ask Comey directly for a personal update on the investigation.
"If he's not under investigation, the country needs to know", Graham continued, "because when he sits down with world leaders, I don't want a cloud over his head".
On February 9, four days before Flynn was sacked as national security adviser, the Washington Post reported that Flynn had "privately discussed US sanctions against Russian Federation with that country's ambassador to the United States during the month before President Trump took office, contrary to public assertions by Trump officials".
"The efforts by a foreign adversary to interfere with and undermine our democratic processes - and those of our allies - pose a serious threat to all Americans", she said. Sheldon Whitehouse, D-R.I., listens at right. One way you can do this is find out who had the information. "Director Comey, would President Trump's tax returns be material to such an investigation?"
