Mark Zuckerberg is being roasted at a Senate hearing on the online child sexual exploitation crisis ... getting up from his hot seat to apologize to victims' families.
The Meta CEO was in the middle of his testimony Wednesday on Capital Hill when he started getting grilled by Sen. Josh Hawley, who bombarded Zuck with questions.
Zuckerberg can barely get a word in as Hawley badgers him on Meta's response, or alleged lack thereof, to kids being sexually exploited online ... and he's pretty much forced to turn around and apologize.
Standing up from his chair, Zuck does a 180 and faces the audience ... which is filled with parents holding up photos of their kids who fell victim to predators using social media.
Zuckerberg indicates it's the first time he's apologized for these sorts of issues happening on Facebook and Instagram ... and he says Meta is taking steps to protect kids.
Other social media executives are testifying too ... including Snapchat's Evan Spiegel, TikTok's Shou Zi Chew, X's Linda Yaccarino and Discord's Jason Citron ... but the most interesting moments have been reserved for Zuck.
Tough day for the Facebook founder -- he's in the hot seat and then some here.
