How to watch Facebook CEO Mark Zuckerberg testify in front of Congress

Facebook CEO Mark Zuckerberg returns to Capitol Hill on Wednesday for his second day of testimony in front of Congress, and the big question remains: Will he bring his own cushion to sit on again?

After a relatively smooth five hours of questioning from a joint panel of two Senate committees on Tuesday, Zuck now faces grilling from the House Energy and Commerce Committee about the "transparency and use of consumer data."

Start time: 10 a.m. ET

Where to watch: The House Energy and Commerce website will broadcast Zuck's testimony live here. VICE News also has a live stream set up on Facebook here.

What you need to know: Zuckerberg provided his witness statement ahead of time here. He'll focus on two main issues:

• The Cambridge Analytica scandal, where as many as 87 million Facebook profiles were compromised as a result of private data being sold. Here's how to tell if your data was stolen.
• Russian interference in the U.S. election: High-ranking Facebook employees have appeared in front of Congress before to discuss Russia's use of fake profiles and political and issue ads to swing the election in favor of Donald Trump, but Zuck never had until Tuesday.
• "It’s clear now that we didn’t do enough to prevent these tools from being used for harm as well. That goes for fake news, foreign interference in elections, and hate speech, as well as developers and data privacy," Zuckerberg wrote in his statement ahead of Tuesday's hearing.

What happened on Tuesday:

• Republican Sen. John Kennedy of Louisiana emerged as the strongman of the Senate Judiciary Committee in his exchanges with Zuckerberg. Most notably, he told the CEO that "your user agreement sucks" and told him to rewrite the terms and conditions in "English and non-Swahili."
• Previously, Facebook had essentially told the public that they agreed to give third-party apps access to their private information, which is what led data analytics firm Cambridge Analytica to get ahold of them in the first place.

• Although Facebook has previously complied with warrants from special counsel Robert Mueller's investigation in Russian meddling in the U.S. election, Zuckerberg himself finally admitted that the company was, indeed, cooperating with the probe. "I know we are working with them," Zuckerberg said.
• Zuckerberg also left his private notes for the hearing on the table, and an Associated Press photographer snapped a photo. He had several sections with bulleted talking points, including responses to tough questions. Read what they are here.
• While Zuck appeared rather calm and collected throughout Tuesday's hearing, that doesn't mean the situation didn't get awkward here and there. First of all, the 33-year-old CEO sat on a comfy cushion, making himself look just a bit taller. Zuckerberg — who's famously said not to trust anyone over 30 — also did not look happy to have to listen to a bunch of senior senators, especially Iowa Sen. Chuck Grassley. Read about some of the other weird moments here.
