FACEBOOK DELETES OVER 250 MORE RUSSIAN ACCOUNTS: Facebook said on Tuesday that it removed over 250 accounts and pages linked to Russian trolls that had attempted to influence U.S. politics around the time of the 2016 election. The company's chief security officer Alex Stamos said in a post that the company removed 70 Facebook and 65 Instagram accounts, as well as 138 Facebook pages linked to the Internet Research Agency (IRA) a Kremlin-linked troll farm whose top employees have been indicted by special counsel Robert Mueller. Stamos said that 95 percent of the accounts that Facebook took down were in Russian and targeted at Russians or Russian speakers in nearby countries like Azerbaijan, Uzbekistan and Ukraine. More than one million Facebook users followed at least one of the now deleted pages and 493,000 Instagram users followed at least one of the now deleted accounts. The pages and accounts collectively spent $167,000 on advertising since Jan. 1 2015, according to numbers provided by Facebook. From CEO Mark Zuckerberg: "Most of our actions against the IRA to date have been to prevent them from interfering in foreign elections. This update is about taking down their pages targeting people living in Russia. This Russian agency has repeatedly acted deceptively and tried to manipulate people in the US, Europe, and Russia -- and we don't want them on Facebook anywhere in the world," the Facebook CEO wrote in a post. Senate Intelligence Committee top Dem Mark Warner (Va.) reacts: "Today's disclosure of more IRA-linked accounts is evidence that the Kremlin continues to exploit platforms like Facebook to sow division, spread disinformation, and influence political debates around the globe," he said in a statement. "I am glad that Facebook is taking some steps to pinpoint and address this activity, but I also expect Facebook and Mr. Zuckerberg, along with other platform companies, to continue to identify Russian troll activity and to work with Congress on updating our laws to better protect our democracy in the future."
House Intelligence Committee top Dem Adam Schiff (Calif.) reacts: "Facebook should proactively notify affected Facebook and Instagram users, including those based in the United States, and continue to do so as future malign activity and content is discovered on its platforms. We also expect Facebook to continue to provide Congress with all relevant information and documents, including these new findings, as part of their ongoing investigation into Russian influence operations," he said in a statement. SENATORS GRILL GRINDR OVER HIV PRIVACY: Two Democratic senators are demanding answers after it was reported that the dating app has been sharing sensitive information about users' HIV status with third parties.

TRUMP KEEPS UP ATTACK ON AMAZON: The president is keeping up his Twitter attacks against Amazon over what he suspects is a cozy deal with the U.S. Postal Service. "I am right about Amazon costing the United States Post Office massive amounts of money for being their Delivery Boy. Amazon should pay these costs (plus) and not have them bourne [sic] by the American Taxpayer. Many billions of dollars. P.O. leaders don't have a clue (or do they?)!" Trump tweeted. Amazon does pay a discounted rate to the USPS due to the volume of its shipping and the postal service has agreed to ship the e-commerce giant's packages on Sundays. But fact-checkers are disputing the notion that the USPS's financial woes can be attributed to Amazon.

"While most everyone agrees on no blocking and no throttling, we need to get the policy right on the impact of prioritization," a committee spokeswoman said in an email. "The goal of this hearing is bringing folks to the table for a good faith conversation on the issue." Republicans have been calling for legislation to fill the void, but net neutrality supporters say that any legislative proposal will fall short of adequate protections. For their part, Democrats are pushing a legislative effort that will nullify the FCC's repeal. POLL FINDS FACEBOOK USERS DON'T TRUST THE COMPANY WITH DATA: A new Huffington Post/YouGov survey has found that a majority of Facebook users are uneasy about how the company handles their data.
