Sen. Dianne Feinstein of California, the top Democrat on the committee, unilaterally released the transcripts on Tuesday, saying Americans had a right to know. When pressed by the committee, Simpson's lawyer Joshua Levy suggested it would be unsafe to do so.
Simpson said he was dubious about Steele's plan to tell the Federal Bureau of Investigation it was a national security issue. When the bureau reinterviewed Steele in early October, agents made it clear, according to Simpson's testimony released Tuesday, that they believed some of what Steele had told them.
Michael Cohen also filed a second lawsuit against Washington research firm Fusion GPS, the company that hired former spy Christopher Steele to investigate Mr Trump's business dealings with Russian Federation.
By the time Steele sat down with the Federal Bureau of Investigation in September, an Australian diplomat had passed to us officials details of his conversation with Papadopoulos, who seemed to know that the Russians possessed hacked Democratic emails. During the debriefing, Steele shared information from his Russian sources, who said Trump had been coordinating with the Russian election-interference campaign of hacking and leaking. But what he does tell investigators is that the individual approached the Federal Bureau of Investigation with similar concerns as Steele.More news: Is PNC Financial's Q4 Earnings Beat Good Enough?
It seems very odd that Fusion GPS, or at least Steele, would expect to have any understanding of internal affairs at the Federal Bureau of Investigation, especially regarding a different case from they were supplying information on.
During his 10 hours of congressional testimony, Mr Simpson was cagey on the origins of claims in the dossier.
Fusion GPS then leaked the salacious and unverified claims made by the Russian sources to intelligence agencies in the United States and UK, to politicians, and to media organizations.

The White House and many Republicans have argued the Fusion GPS dossier and claims of collusion are a political smear, devoid of credibility.
Since then, multiple news outlets and government agencies have confirmed that Russian Federation hacked into the Democratic National Committee with the goal of helping to elect Trump, resulting in an investigation being set up led by special counsel Robert Mueller, the former head of the FBI.
Trump has a long history of anti-Jewish controversies. Republican Sens. Charles Grassley, Iowa, committee chair, and Lindsey Graham, S.C., also on the committee with Feinstein, have referred Simpson for criminal prosecution.
Grassley, not entirely amused, told CNN he "doesn't want to know" what Trump meant by the statement. Chuck Grassley, who had previously refused to release the contents of the interview.

Feinstein is the ranking Democrat on the Senate Judiciary Committee, which interviewed the head of a research firm called Fusion GPS in August.
