President Donald Trump, stepping up his criticism of technology firms he says are favoring liberal points of view, said they may be in a \u201cvery antitrust situation\u201d but repeatedly said he can\u2019t comment publicly on whether they should be broken up. \u201cI won\u2019t comment on the breaking up, of whether it\u2019s that or Amazon or Facebook,\u201d Trump said in an Oval Office interview\u00a0Thursday\u00a0with Bloomberg News. \u201cAs you know, many people think it is a very antitrust situation, the three of them. But I just, I won\u2019t comment on that.\u201d Trump reiterated for the third day his accusation that \u201cconservatives have been treated very unfairly\u201d by Alphabet Inc.\u2019s Google. \u201cI tell you there are some moments where we say, \u2018Wow that really is bad, what they\u2019re doing.\u2019\u201d Trump\u2019s latest attack on the technology companies began\u00a0Tuesday\u00a0when he claimed without providing evidence that Google\u2019s news search function favored liberal over conservative outlets, tweeting that \u201cThis is a very serious situation-will be addressed!\u201d Later, in a meeting in the Oval Office, he told reporters that Alphabet Inc.\u2019s Google, Facebook Inc. and Twitter Inc. \u201care treading on very, very troubled territory.\u201d On Wednesday, he tweeted a video, with the hashtag "#StopTheBias," which purported to show that Google promoted President Barack Obama\u2019s annual State of the Union address on its homepage but did not give a boost to Trump\u2019s. Google said in a statement that it promoted Trump\u2019s 2018 address, but didn\u2019t post a tout to either his or Obama\u2019s speeches to Congress after they were first elected, which are not technically State of the Union addresses. The company says its news searches are designed to give users relevant answers and don\u2019t favor any political point of view. Trump continued with the topic at a rally in Evansville, Indiana,\u00a0on Thursday\u00a0night. "I\u2019ve made it clear we as a country cannot tolerate" censorship and "rigged search results," the president said. "We\u2019re not going to let them control what we can and cannot see, read, and learn from." Earlier: Trump Warns Tech Giants \u2018Be Careful,\u2019 Claiming Rigged Searches The company had no immediate response to Trump\u2019s suggestion it may be violating antitrust laws but the same point was raised earlier in the day by a top Republican lawmaker. Republican Senator Orrin Hatch of Utah\u00a0on Thursday\u00a0asked U.S. Federal Trade Commission Chairman Joseph Simons to re-examine Google\u2019s conduct in search and digital advertising, saying reports of potentially anticompetitive conduct are \u201cdisquieting.\u201d Google declined to comment on Hatch\u2019s letter. After Trump\u2019s attack this week, the company said its search function is not used to set a political agenda and isn\u2019t biased against any ideology. The FTC previously investigated Google over whether the company skewed search results to favor its own services. The agency closed that case in 2013 without bringing an enforcement action after Google agreed to stop certain practices, including removing restrictions on the use of its online search advertising platform. The decision to close the case, made under the administration of former President Barack Obama, disappointed some companies and consumer groups who claimed Google abused its dominance. The FTC is now led by Simons, who has expressed a willingness to examine the conduct of technology platforms. \u201cIn the past, Google has offered arguments that its conduct is procompetitive,\u201d Hatch wrote. \u201cBut much has changed since the FTC last looked at Google\u2019s conduct regarding search and digital advertising.\u201d Calls for comment to representatives for Amazon and Facebook were not immediately returned. The companies, which offer popular free services, have said they face intense competition and deny they\u2019re harming consumers. Google may hear more about the bias allegations and other issues alongside executives from Facebook and Twitter at a hearing on Russian election meddling on\u00a0Sept. 5.
