The Trump campaign has repeatedly downplayed the firm's role in the campaign.
The company has suspended its CEO Alexander Nix "with immediate effect, pending a full, independent investigation".
Some Wall Street analysts believe Facebook won't suffer any long-term setbacks from the latest controversy.
Cambridge Analytica released a statement on Tuesday evening. "We ran all the digital campaign and our data informed their strategy", Nix was filmed and told the undercover reporter during a meeting in a London hotel.
"In the view of the Board, Mr. Nix's recent comments secretly recorded by Channel 4 and other allegations do not represent the values or operations of the firm and his suspension reflects the seriousness with which we view this violation", the board said in the statement. It's a myth that users own the data and content they post on Facebook, and control how it's shared.
Zuckerberg is expected to respond to the committee by 26 March.
In the U.S., members of Congress had called on Zuckerberg to testify about Facebook's actions.
The request to appear comes as British data protection authority was seeking a warrant to search the London offices of Cambridge Analytica.
And the parliamentary committee investigating fake news announced that it was summoning Facebook founder Mark Zuckerberg to give evidence, accusing the company of giving "misleading" answers at a previous hearing on the issue.
But the firm's reputation took a fresh hit on Monday, with the broadcast of secret footage showing Nix saying it could entrap politicians in compromising situations with bribes and sex workers.
Cambridge Analytica worked to help the Trump campaign identify and mobilize potential voters during the 2016 presidential contest.
"I certainly feel that the air of mystery and negativity that surrounds the work of Cambridge is misfounded and, as the CEO, I take responsibility for that".
