Campaign associates reportedly worked with Russian links to release information damaging to former Democratic presidential candidate Hillary Clinton, according to USA officials cited by CNN.

CBS News has learned that some members of Congress want former British spy Christopher Steele to testify before the House Intelligence Committee investigating whether the Trump Campaign coordinated with the Russians during the 2016 election.

The information being investigated is said to comprise of travel, business and phone records as well as accounts of meetings and "human intelligence".

CNN notes that the Federal Bureau of Investigation was already looking into the affairs of four former Trump campaign associates-Michael Flynn, Paul Manafort, Roger Stone and Carter Page-for contacts with Russians known to USA intelligence.

In this vein, Ardayev also drew attention to the fact that the U.S. officials mentioned by CNN said that "the information was not conclusive and that the investigation is ongoing".

"President Trump owes the American people and President Obama more than just an explanation, but an apology", Schumer told the press.

White House Press Secretary Sean Spicer is disputing claims that FBI Director James Comey fact-checked President Trump during Monday's congressional hearing examining Russia's influence in the 2016 election. And while Rogers and Comey refused to say whether any specific individuals are under investigation, Carson says it "doesn't look good" that Trump campaign adviser Roger Stone was tweeting about looming Wikileaks revelations from within Hillary Clinton's campaign before those leaks actually appeared.

"FBI Director Comey refuses to deny he briefed President Obama on calls made by Michael Flynn to Russian Federation".

But neither can the nation assume that when James Clapper, the former director of national intelligence, reported no evidence of "collusion" between the Trump campaign and the Russians, at least through the end of the Obama term, that was the final word on the subject.

"The last line of [the CNN report] said, 'The FBI can not yet prove that collusion took place, '" responded Spicer, who frequently battles with CNN over its reporting on Trump's presidency.

Nunes's weird decision to personally brief the president on this information before discussing it with members of the committee renewed calls for a congressional select committee or independent commission to probe the Trump/Russia allegations.

Barrett added that Comey's testimony hinted that it's likely the investigation goes unresolved for months before any larger conclusions are made, if ever at all.
