Facebook COO Sheryl Sandberg joined her boss Mark Zuckerberg in expressing "regret" about the company's relationship with Cambridge Analytica. She also wrote on Facebook about a responsibility to protect user data and pledged an audit of apps with access to "large amounts" of user data.

And if we find that developers misused personally identifiable information, we'll ban them from our platform and we'll tell the people who were affected.

Her full post:

Sharing Mark's post addressing the Cambridge Analytica news. As he said, we know that this was a major violation of peoples' trust, and I deeply regret that we didn't do enough to deal with it. We have a responsibility to protect your data - and if we can't, then we don't deserve to serve you.
We've spent the past few days working to get a fuller picture so we can stop this from happening again. Here are the steps we're taking. We're investigating all apps that had access to large amounts of information before we changed our platform in 2014 to dramatically reduce data access. And if we find that developers misused personally identifiable information, we'll ban them from our platform and we'll tell the people who were affected.
We're also taking steps to reduce the data you give an app when you use Facebook login to your name, profile photo, and email address. And we'll make it easier for you to understand which apps you've allowed to access your data.
You deserve to have your information protected - and we'll keep working to make sure you feel safe on Facebook. Your trust is at the core of our service. We know that and we will work to earn it.

Biden officials are working to root out the systematic fraud in unemployment and Paycheck Protection Program claims that plagued the Trump administration’s efforts to boost the economy with coronavirus relief money, Gene Sperling told House committee chairmen privately this week.

Why it matters: President Biden just signed another $1.9 trillion of aid into law, with Sperling tapped to oversee its implementation. And the administration is asking Congress to approve another $2.2 trillion for the first phase of an infrastructure package.

Nicholas Burns, a career diplomat, is in the final stages of vetting to serve as President Biden’s ambassador to China, people familiar with the matter tell Axios.

Why it matters: Across the administration, there's a consensus the U.S. relationship with China will be the most critical — and consequential — of Biden's presidency. From trade to Taiwan, the stakes are high. Burns could be among the first batch of diplomatic nominees announced in the coming weeks.
