NEW DELHI: Barely two days after US President Donald Trump returned from his first trip to India, BJP general-secretary (organization) B L Santhosh on Thursday caused the ruling party some embarrassment with his tweet on the US presidential polls.In a tweet against Democrat frontrunner Bernie Sanders , Santhosh suggested that the BJP may be “compelled” to play a role in the US presidential elections slated for later this year.The tweet, which was later deleted, came in response to Sanders' criticism of Trump.“How much ever neutral we wish to be you compel us to play a role in the Presidential elections. Sorry to say so … But you are compelling us,” he had tweeted.He was replying to Sanders’s tweet posted on Wednesday that said, “Over 200 million Muslims call India home. Widespread anti-Muslim mob violence has killed at least 27 and injured many more. Trump responds by saying, “That’s up to India. This is a failure of leadership on human rights.”While BJP has not reacted to Santhosh’s tweet that spoke of India taking clear sides in the American elections, which is clearly seen as a diplomatic faux pas, the party general secretary removed his tweet within hours of posting it, evidently realizing that he had taken a wrong step by making the statement on social media.Sanders took on Trump for his reaction at the press conference here on questions about the clashes during his visit. Responding to reporters, Trump had said, "As far as the individual attacks, I heard about it, but I didn't discuss that with him (PM Modi). That's up to India."Another Democrat candidate, Senator Elizabeth Warren , had also criticized the violence over the Citizenship Amendment Act protests in Delhi. The violence in northeast Delhi, which has left 32 dead and over 200 injured, cast a shadow on Trump's two-day visit, which was viewed as his outreach to the Indian American community, a sizeable group of voters, as he faces a re-election bid in the US presidential polls later this year.During his visit, President Trump lavished praise on India and Prime Minister Narendra Modi, calling him a "great friend" and a "very popular leader".
