Zuckerberg is testifying at a joint hearing of the Senate Judiciary and Commerce committees on Tuesday, followed by a hearing before the House Energy and Commerce Committee on Wednesday.

The 33-year-old tech executive is expected to face tough questioning from lawmakers over how Facebook handles users’ data and questions about the improper gathering of the data of nearly 90 million users by a British firm.

Lawmakers are expected to grill Zuckerberg over why Facebook let third parties collect data on its users without their express consent and why the company didn’t ensure that Cambridge Analytica — a firm used by the Trump campaign — deleted the improperly collected user data.

Facebook Chief Operating Officer Sheryl Sandberg said late last week that the company has "different forms of opt-out” but doesn’t give users the option to completely opt out of having their data be used in targeted advertising.

"We don't have an opt-out at the highest level. That would be a paid product," Sandberg told NBC News on Thursday.

She added that while Facebook had received assurances that Cambridge Analytica deleted the data, “what we didn't do was the next step of an audit and we are trying to do that now."

It was previously estimated that the British research firm hired by the Trump campaign had improperly harvested data from about 50 million Facebook users, but new estimates last week revealed that about 87 million users had data taken.

More broadly, the company said most of its 2 billion users could have had their public data scraped by third parties.

“Given the scale and sophistication of the activity we’ve seen, we believe most people on Facebook could have had their public profile scraped in this way,” said Mike Schroepfer Facebook's chief technology officer.

Ahead of his Capitol Hill appearances, Zuckerberg announced Friday that Facebook would start verifying advertisers who seek to run political ads on its platform, as well as requiring users who manage any large page to be verified.

Balanced budget

The House is expected to vote on a balanced budget amendment to the Constitution just weeks after Congress passed a $1.3 trillion spending package that is projected to add billions to the deficit.

The amendment, introduced by House Judiciary Chairman Bob Goodlatte (R-Va.), requires a "true majority" to pass tax increases and a three-fifths majority in both chambers to increase the debt limit.

"I commend the decision made by House leadership to bring H.J.Res. 2 to the floor for a vote. I challenge my colleagues in the House and Senate to do what is morally right and responsible by passing this amendment and sending it on to the states for ratification," Goodlatte said in a statement.

The measure has almost no chance of becoming law. It needs Democratic support in the Senate and ratification from the majority of states.

The tax bill is projected to add more than $1 trillion to the deficit, though Republicans argue economic growth will make up for the spending.

Republicans are facing backlash from their conservative base over last month’s omnibus spending bill, which Trump lambasted and threatened to veto before ultimately signing.
