Mark Zuckerberg has finally caved to pressure to testify before Congress about the social network’s data-privacy scandal.

Facebook’s 33-year-old chief executive is in talks with the House Energy and Commerce Committee to “determine a day and time … to testify,” Elena Hernandez, a spokeswoman for the panel, confirmed in a Tuesday statement.

Zuckerberg’s decision comes after repeated calls by US lawmakers for him to submit to a Capitol Hill grilling.

In addition, under the heat from Washington, at least 37 states and UK’s Parliament, Facebook’s stock has wilted, falling 21.2 percent from its 2018 high on Feb. 1.

Since the scandal broke, Zuckerberg’s net worth has fallen by about $13 billion over 10 days, to roughly $62 billion. On Tuesday, shares of the Menlo Park, Calif., company tanked 4.9 percent, to $152.22.

Zuckerberg’s trip to DC promises a spectacle, as he scrambles to contain the damage over revelations that Facebook spilled the data of over 50 million users to Cambridge Analytica, a firm with ties to the Trump campaign.

Sen. Chuck Grassley (R-Iowa), chairman of the Judiciary Committee, also invited Zuckerberg — along with Google CEO Sundar Pichai and Twitter CEO Jack Dorsey — to a hearing on data privacy on April 10.

Sen. John Thune (R-SD), chairman of the Commerce Committee, and Sen. Bill Nelson (D-Fla.), the committee’s ranking member, have said they would work with Facebook “to find a suitable date for Mr. Zuckerberg to testify in the coming weeks.”

The tech mogul had previously been coy about whether he would volunteer testimony.

In an interview with CNN last week, Zuckerberg said he was “happy to … if it’s the right thing to do,” before hedging further: “What we try to do is send the person at Facebook who will have the most knowledge.”

“We believe, as CEO of Facebook, [Zuckerberg] is the right witness to provide answers to the American people,” Rep. Greg Walden (R-Ore.), chairman of the Energy and Commerce Committee, and Rep. Frank Pallone (D-NJ), the ranking member, shot back.

There were also reports on Tuesday that Facebook was shopping for top-notch Washington lobbyists.

That move may have been pushed along by Monday’s announcement by the Federal Trade Commission that it has launched a probe into whether Facebook violated the terms of a 2011 settlement entered into after an earlier data leak.

Separately Tuesday, Cambridge Analytica whistleblower Christopher Wylie, in testimony to UK lawmakers, said he believes the amount of users whose private info was accessed was “substantially higher than” 50 million.

Wylie also testified that the data firm worked with Palantir, a data company headed by Facebook board member and prominent Trump supporter Peter Thiel.

Palantir has denied the accusation, saying that it “never had a relationship” with Cambridge Analytica.

On the same day as Wylie’s testimony in London, Zuckerberg refused British lawmakers’ requests that he testify on the scandal — a rebuff that the head of a parliamentary committee called “astonishing.”

Facebook said it would instead send a Zuckerberg deputy.
