U.S. President Donald Trump
U.S. President Donald Trump accused Twitter Inc on Thursday of restricting the visibility of prominent Republicans on its platform, without providing evidence, and he promised to investigate.
"Twitter 'SHADOW BANNING' prominent Republicans. Not good. We will look into this discriminatory and illegal practice at once!" the Republican president wrote in a Twitter post.
The practice involves limiting the visibility of a user in search results, specifically in the auto-populated dropdown search box on Twitter.
Trump's comments followed a Vice news report on Wednesday that Republican National Committee Chairwoman Ronna McDaniel and other Republicans including Donald Trump Jr's spokesman were being "shadow banned."
The United States has opened a path for India to avoid sanctions for buying arms from Russia, business leaders and experts said, almost a year after U.S. President Donald Trump signed a law penalising such trade.India uses a large amount of Russian military equipment, from combat planes to ships and submarines, and is in the final stages of negotiating a $6 billion deal to buy S-400 long range surface to air missile systems from Russia.Under the Countering America's Adversaries Through Sanctions Act (CAATSA) that Trump signed in August, any country trading with Russia’s defence and intelligence sectors faces secondary sanctions.The law is designed to punish Russian President Vladimir Putin for the 2014 annexation of Crimea from Ukraine, involvement in the Syrian civil war and meddling in the 2016 U.S. presidential election.Germany hails US-EU trade reprieveBut the U.S. Congress reached an agreement this week laying out conditions under which Trump can seek a waiver for allies. The administration has to certify that a country is reducing arms imports from Russia and is expanding defence cooperation with the United States.India meets both those conditions, analysts and business leaders in New Delhi and Washington said.India's government declined immediate comment, and a defence official said the U.S. Congress had still to vote on the modifications to the legislation which would then be signed by Trump into law.Nisha Biswal, president of the U.S.-India Business Council (USIBC), said the U.S. move would help protect its strategic relationship with India.US, EU reach trade pact after retaliatory tariffs"At a time when India is focusing on growing defence ties with the U.S., we applaud Congress for also focusing on protecting this strategic partnership," Biswal said.Jeff Smith, a south Asia expert at The Heritage Foundation, said the changes were a "meaningful and positive step forward"."It reduces the possibility an Indian arms purchase from Russia will trigger CAATSA sanctions, a situation both the administration and most of Capitol Hill are keen to avoid," he said.India has in recent years diversified its arms purchases, turning to the United States and Israel for modern equipment. It has ordered $15 billion of weapons from the U.S. over the past ten years and U.S. companies are bidding for contracts for fighter planes and helicopters worth billions of dollars.

"The notion that social media companies would suppress certain political points of view should concern every American. Twitter owes the public answers to what’s really going on," McDaniel wrote on Twitter.
Twitter did not have a comment on Trump's tweet but a spokesperson said the company does not "shadow ban."
"We are aware that some accounts are not automatically populating in our search box, and shipping a change to address this," the spokesperson said in a statement." Twitter said the technology used is based on user behavior not political views.
Twitter instituted a policy change on July 12 to increase the service's credibility and reduce suspected fraud. That change cost its 100 most popular users about 2 percent of their followers, on average, according to social media data firm Keyhole.
Twitter shares, already lower in premarket trading after Facebook Inc's disappointing earnings late Wednesday damped enthusiasm for technology and social media stocks, dipped a bit further and volume rose slightly after Trump's tweet at 7:46 a.m. The stock was last down 3.2 percent.
