A company that evaluates news outlets and websites to see which produce reliable journalism says it's under attack by the Trump administration. NewsGuard has sued the Federal Trade Commission over an agency investigation that the company says is threatening its livelihood. NewsGuard's ratings system is used to help advertisers and artificial intelligence companies decide which news sites they can trust with their business. Conservative groups and the television network Newsmax says the ratings system is trying to censor conservative thought. The FTC says its investigation of NewsGuard is part of a broader effort to see whether advertiser boycotts violate antitrust laws.
