Patel's comment came as the Delhi Police on Tuesday arrested NewsClick founder Prabir Purkayastha and Human Resources head Amit Chakravarty after searching several locations and questioning many journalists linked to the portal, in connection with a case filed under the Unlawful Activities (Prevention) Act (UAPA).
This was following allegations that the portal received money for pro-China propaganda.
Reacting to the development, Patel said, "Separately, of course though, the US government strongly supports the robust role of the media globally, including social media, in a vibrant and free democracy."
"We raise concerns on these matters with the Indian government, with countries around the world, through our diplomatic engagements that are at the core of our bilateral relationship," he said.
"We have urged the Indian government and have done so not just with India, but other countries as well, about the importance of respecting the human rights of journalists, including freedom of expression both online and offline," he said.
The news website had recently hit the headlines for allegedly receiving money from US millionaire Neville Roy Singham for pro-China propaganda in India, according to a report by New York Times.
"In New Delhi, corporate filings show, Mr Singham's network financed a news site, NewsClick, that sprinkled its coverage with Chinese government talking points," The New York Times then wrote.
