The way the the former CEO of Cambridge Analytica described Republicans on the House Intelligence Committee is "all too accurate," House Intelligence Committee ranking member Adam Schiff Adam Bennett SchiffTop Democrats call for DOJ watchdog to probe Barr over possible 2020 election influence Overnight Defense: Top admiral says 'no condition' where US should conduct nuclear test 'at this time' | Intelligence chief says Congress will get some in-person election security briefings Overnight Defense: House to vote on military justice bill spurred by Vanessa Guillén death | Biden courts veterans after Trump's military controversies MORE (D-Calif.) said Tuesday.

Alexander Nix, the former head of the research firm, painted Republicans on the committee as indifferent toward the information he gave the panel in his testimony last year.

“After five minutes — done,” Nix said of his testimony.

“They’re politicians, they’re not technical. They don’t understand how it works,” he said in an in-house exchange captured by an undercover Channel 4 News reporter.

Schiff, the top Democrat on the panel, said the questioning of Nix by the committee was cursory.

"We have serious questions about how accurate Mr. Nix was in his testimony. But you know, my colleagues had a habit of asking three questions: Did you conspire, did you collude, did you coordinate with Russians? And if the answer was 'no,' they were pretty much done," Schiff said in a statement.

The spotlight has shifted to Cambridge Analytica after reports that the firm obtained Facebook data on more than 50 million Americans that were then used in their work on President Trump Donald John TrumpBiden leads Trump by 36 points nationally among Latinos: poll Trump dismisses climate change role in fires, says Newsom needs to manage forest better Jimmy Kimmel hits Trump for rallies while hosting Emmy Awards MORE's campaign. The data were provided by a researcher who had collected it with an app but was not supposed to share it.

Schiff, who is trying to push forward the Russia inquiry despite the decision by Republicans to end it, is requesting a second appearance by Nix, and testimony from other top Cambridge Analytica executives.

He said Democrats' requests to bring Nix back before the panel, and to seek testimony from other Cambridge executives, were rejected by Republicans. But he noted that a Cambridge Analytica whistleblower has agreed to be interviewed by Democrats as they continue their investigation.

"And if his testimony is what it has been reported, then it's deeply at odds with Mr. Nix’s testimony. And we’re going to need to get to the bottom of it," Schiff said. "It certainly appears that Mr. Nix and Cambridge Analytica misused the private data of tens of millions of Americans."

Schiff reportedly sent a request for Christopher Wylie, the whistleblower who revealed the use of the data. He said that if Wylie's claims about the company's improper data usage is correct, the committee will "need to get to the bottom" of the matter.

Nix, who claimed that the data firm "did all the research, all the data, all the analytics, all the targeting" for the Trump campaign, was suspended from Cambridge Analytica this week.
