<strong>WASHINGTON (AP) \u2014<\/strong> The Latest on testimony before a congressional committee by the CEOs of Facebook, Apple, Amazon and Google (all times local):\n6:30 p.m.\nDemocratic chairman of a House antitrust panel says Facebook is making money off dangerous lies that could have deadly consequences.\nRep. David Cicilline lodged the accusation at the tech company's CEO, Mark Zuckerberg, Wednesday during a congressional hearing also featuring testimony from the heads of Apple, Amazon and Google.\nCicilline noted a series of popular conspiracy theories \u2014 including that the coronavirus pandemic is a hoax \u2014 that have thrived on Facebook's platform during the deadly virus' grip across the globe.\n"It brings the most activity which, of course, produces great profit," Cicilline said to Zuckerberg.\nZuckerberg offered assurances that the social network's users don't want to see misinformation in their feeds, so the company has taken big steps to scrub its site of inaccurate coronavirus claims. But that only invited more push back from Cicilline, noted out that just on Monday the company struggled to take down a video of pro-Trump doctors peddling misleading claims that Americans don't need to wear masks and an unproven anti-malaria drug, hydroxychloroquine, as a sure-fire way to treat the virus.\nThe video raked in more than 20 million views before Facebook started removing it, with dozens of other versions of it still cropping up. Earlier in the hourslong hearing, GOP congressmen had complained that Facebook, YouTube and Twitter took down that same video at all, describing it as censorship.\nNodding to that political tightrope he's walking on, Zuckerberg defended the company's misinformation policies, "we've been quite aggressive in taking some of that down, as some of the questioning from the other side of the aisle has shown so far."\n___\n5:20 p.m.\nU.S. lawmakers have repeatedly ripped the CEOs of Apple, Amazon, Google and Facebook while likening them to copycats, liars, bullies, drug dealers and traitors in an attempt to prove it's time to crack down on their technology powerhouses.\nThe barrage of unflattering comparisons and allegations of misconduct unfolded Wednesday during an extraordinary hearing that summoned Apple CEO Tim Cook, Amazon CEO Jeff Bezos, Google CEO Sundar Pichai and Facebook CEO Mark Zuckerberg before a congressional committee. The committee is looking into allegations that the companies have been abusing the popularity of their products and services to stifle competition and innovation.\nAll four CEOs appeared via video because of the pandemic.\nLawmakers were particularly harsh on Google, whose dominant search engine serves as the main gateway to the internet, and Facebook, whose social network with more than 2 billion people has has had trouble blocking efforts to spread bogus information in attempt to sway elections and sow social unrest. Both Pichai and Zuckerberg insisted their companies have worked hard to fix any problems on their services and strive to improve their mostly free services to keep their users happy to they can continue to sell the ads that bring in most of their revenue.\n___\n4:45 p.m.\nA key House lawmaker investigating Big Tech's power is squarely targeting Amazon.\nRep. David Cicilline, a Democrat, told Amazon CEO Jeff Bezos at a hearing Wednesday that evidence shows that the e-commerce giant is only interested in dominating the market and is "fundamentally anti-competitive."\nCicilline said "Congress must take action."\nAs chair of a House Judiciary panel, Cicilline is looking toward possible new legislation to update century-old antitrust laws. But Republican Rep. James Sensenbrenner rejects the idea that legislation is needed \u2014 showing it could be a difficult mission for Democrats in Congress.\nThe Bezos, along with the CEOs of Apple, Facebook and Google were answering lawmakers' questions about their companies' practices as a House panel caps its yearlong investigation of market dominance in the technology industry.\n___\n3:50 p.m.\nAmazon founder Jeff Bezos says he can't guarantee that the company isn't accessing seller data to make competing products, an allegation that the company and its executives had previously denied.\nHis comments came Wednesday during a congressional hearing into the market dominance of four tech giants \u2014 Amazon, Google, Facebook and Apple.\nRegulators in the U.S. and Europe have been scrutinizing Amazon's relationship with the businesses that sell on its site and whether the online shopping giant has been using data from the sellers to create its own private-label products.\n"We have a policy against using seller specific data to aid our private label business," said Bezos, in a response to a question from Rep. Pramila Jayapal, a Democrat from Amazon's home state of Washington. "But I can't guarantee to you that that policy hasn't been violated."\nA Wall Street Journal article from April quoted Amazon employees who said they did have access to seller data to make competing products, including a car trunk organizer that Amazon copied.\nBezos said he was aware of the article and is still looking into the allegations.\n"I'm still not satisfied that we've gotten to the bottom of it," he said.\n___\n3:30 p.m.\nFacebook CEO Mark Zuckerberg is again being put on the defensive in a congressional hearing over the social network's role as a conduit for Russian interference in the 2016 presidential election.\nAnd Rep. Jamie Raskin, a Maryland Democrat, has brought the issue current with concerns that right-wing groups are using Facebook to infiltrate the Black Lives Matter movement and to spread anti-Semitic propaganda.\nZuckerberg says Facebook uses sophisticated technology to intercept hate speech, often before it's seen on the platform. "It hurts our business," he said.\nZuckerberg's comments came at hearing that also featured Amazon CEO Jeff Bezos, Apple CEO Tim Cook and Google CEO Sundar Pichai. The CEOs are answering for their companies' practices as a House panel caps its yearlong investigation of market dominance in the industry.\n___\n2:45 p.m.\nFacebook internal company documents are being deployed against CEO Mark Zuckerberg by lawmakers asserting that the company has gobbled up rivals to squelch competition.\nRep. Jerrold Nadler, the Democrat who heads the House Judiciary Committee, told Zuckerberg at a hearing Wednesday that documents obtained from the company "tell a very disturbing story" of Facebook's acquisition of the Instagram messaging service.\nHe said the documents show Zuckerberg called Instagram a threat that could "meaningfully hurt" Facebook.\nZuckerberg responded that Facebook viewed Instagram as both a competitor and a "complement" to Facebook's services, but also acknowledged that it competed with Facebook on photo-sharing. Some critics of Facebook have called for the company to divest Instagram and its WhatsAPP messaging service.\nThe questioning came at a congressional hearing that also featured Amazon CEO Jeff Bezos, Apple CEO Tim Cook and Google CEO Sundar Pichai.\n___\n2:30 p.m.\nThe chairman of a Congressional committee investigating the power of major technology companies accused Google of leveraging its dominant search engine to steal ideas and information from other websites and manipulating its results to drive people to its own digital services to boost its profits.\nRep. David Cicilline peppered Google CEO Sundar Pichai with the allegations of abusive behavior while grilling him Wednesday during a hearing that is also putting Amazon CEO Jeff Bezos, Apple CEO Tim Cook and Facebook CEO Mark Zuckerberg on virtual hot seats while answering questions posed through a video stream.\nPichai repeatedly deflected Cicilline's attacks by asserting that Google tries to provide the most helpful and relevant information to the hundreds of millions of people who use its search engine each day. He said this is part of its effort to keep them coming back instead of defecting to a rival service, such as Microsoft's Bing.\nPichai struggled to answer one question about whether Google threatened to dump Yelp from its search engine database after the restaurant review site told Google to stop scraping its site for content. Yelp raised that issue about a decade ago before before Pichai became CEO in 2015.\n___\nThis story has been updated to correctly identify the CEO of Amazon in the item on unflattering comaparisons.
