Google\u2019s Sundar Pichai is facing bipartisan criticism for refusing to testify at a Senate Intelligence Committee hearing next week, but the panel\u2019s chairman signaled he\u2019s unlikely to issue a subpoena to force the chief executive officer to appear. \u201cI don\u2019t normally subpoena people to be part of the solution," Senator Richard Burr of North Carolina said Tuesday when asked if he\u2019s considering such a step. "Google chooses not to participate and being part of the solution. That\u2019s a decision they made.\u201d Twitter Inc. CEO Jack Dorsey and Facebook Inc. Chief Operating Officer Sheryl Sandberg are said to be planning to testify at the Sept. 5 Senate committee hearing on social media and Russian meddling. Alphabet Inc.\u2019s Google previously announced it would send Kent Walker, its senior vice president for global affairs. The company said Tuesday that Walker, who\u2019s overseeing its efforts to tackle foreign interference, will be in Washington and available to meet with lawmakers on the day of the hearing. But Burr - who had asked Pichai to testify - had said Thursday, Aug. 23, that Walker wasn\u2019t sufficiently high up in the company, according to a panel spokeswoman. The senator said it\u2019s up to Google whether to send someone acceptable to appear before the committee, which is investigating Russian interference in U.S. elections and its manipulation of social media. Open Chair \u201cThe chair will be there, the nameplate will be there,\u201d Burr said. \u201cIf they want us to fill in a name, I will.\u201d Lawmakers\u2019 frustration with Google comes as President Donald Trump opened criticism of the dominant internet search provider on another front. He asserted in a tweet on Tuesday that Google promotes anti-Trump search results and suppresses pro-Trump news. The company responded that \u201csearch is not used to set a political agenda and we don\u2019t bias our results toward any political ideology.\u201d Donald J. Trump @realDonaldTrump Google search results for \u201cTrump News\u201d shows only the viewing\/reporting of Fake News Media. In other words, they have it RIGGED, for me & others, so that almost all stories & news is BAD. Fake CNN is prominent. Republican\/Conservative & Fair Media is shut out. Illegal? 96% of.. Sent via Twitter for iPhone. Trump told reporters later Tuesday that Google, Facebook and Twitter had \u201cbetter be careful\u201d because they \u201care treading on very, very troubled territory\u201d by favoring liberal viewpoints. Burr was joined by Intelligence Committee members of both parties in criticizing Pichai\u2019s plans to be a no-show next week. Senator Mark Warner of Virginia, the Intelligence panel\u2019s top Democrat, said Google is making a \u201cgreat mistake\u201d by offering to send Walker and not a higher-level official. \u201cThat\u2019s not the level that we should have,\u201d he said. Senator Angus King, a Maine independent who caucuses with Democrats, said Google and the other companies should all send their CEOs. \u201cThis is the United States Senate, this is an important issue, and we deserve to hear from the decision-makers, not the people who carry out the decisions," King said. The panel previously held a hearing with lawyers for Facebook, Twitter and Google. Facebook CEO Mark Zuckerberg testified at House and Senate committee hearings in April though not before the Senate Intelligence panel.
