WASHINGTON -- CBS News has confirmed that Christopher Steele produced the memo containing unsubstantiated claims that Russia has compromising personal and financial information about President-elect Trump.

Christopher Steele

Steele is a former British intelligence officer who works for Orbis Business Intelligence, a private investigation firm in London.

Orbis was originally hired by Fusion GPS, a Washington-based research firm working for an unknown client.

The unverified claims circulated widely in political and media circles. Last week, the U.S. intelligence community included a summary of the information in a classified briefing to Trump, who said the memo was phony.

Trump: It's a "disgrace" claims on Russian intel were leaked

“I think it was disgraceful that the intelligence agencies allowed any information that turned out to be so false and leak out,” Trump said in his Wednesday press conference.

“That’s something that Nazi Germany would have done and did do.”

Director of National Intelligence James Clapper phoned Trump Wednesday night. In a statement, Clapper said he expressed his “profound dismay” at the leaks and “emphasized that (the unverified document) is not a U.S. intelligence community product.”

President Obama and Vice President Biden also received the briefing. On MSNBC, the vice president was asked if including the claims was appropriate.

“It was their obligation to inform not only us but the president-elect that this was out there so that it didn’t come out of the blue and have any impact on the conduct of our foreign policy. They were clear that they just mentioned it, they made no judgment about it,” Biden said.

Watch full: Donald Trump speaks about Russian hack intel, election

After finally acknowledging Russia was responsible for the election-year hack of Democratic officials, Trump named former New York City Mayor Rudy Giuliani as a top cybersecurity consultant on Thursday.

“My job is going to be to find the corporate leaders, people who are working on the new solutions, and from time to time set up meetings with the president and whomever else he wants so that they can give him the benefit of what they’re doing,” Giuliani said.

House Speaker Paul Ryan told CBS News he understands Trump’s frustration, calling the leaks and subsequent media frenzy unfair.

But the speaker also said he would not have suggested intelligence agencies used Nazi tactics in this or any other matter.
