Republicans on the House Intelligence Committee voted down a Democratic proposal to hold a hearing with Facebook's Mark Zuckerberg and other tech CEOs, according to the panel's ranking member, Adam Schiff.
The Democratic effort came amid a firestorm over revelations that Trump-linked Cambridge Analytica improperly obtained information on some 50 million Facebook users.
Schiff, however, said House Intel Democrats are finalizing plans for an interview with Christopher Wylie, the whistleblower in the Cambridge Analytica case.
Spokespeople for House Intelligence Chairman Devin Nunes and the panel's top Russia investigator Mike Conaway didn't immediately respond to a request for comment.
House Intelligence Republicans also voted today to end their investigation into Russian interference in the 2016 presidential election, declaring that a string of contacts between Donald Trump's associates and Russian government affiliates fell short of collusion.
Earlier today, leaders of the House Energy and Commerce Committee became the first in Congress to say they will summon Zuckerberg to testify about Cambridge Analytica.
Asked about the Facebook controversy today, House Judiciary Chairman Bob Goodlatte declined to comment, referring questions to his staff. A Judiciary Committee aide also declined to comment on the prospect of a Facebook hearing.
