Ahead of US President Donald Trump's India visit later this month, four top US senators have written to US Secretary of State Mike Pompeo, expressing concern about the internet curbs in Kashmir more than six months after Jammu and Kashmir's special status was scrapped under Article 370, as well the preventive detentions of political leaders. In their letter, the senators also express concern over the Citizenship (Amendment) Act or CAA that triggered protests across the country.
