RT documentarian Konstantin Rozhkov was stopped by US federal agents at a New York airport soon after arriving in the country on Wednesday, where he was subjected to a three-hour interrogation and forced to provide access to his electronics.

"The journalist was requested to open all electronic media, as well as explain publicly available information, including about him receiving the Russian-made vaccine, Sputnik V," the embassy said in a statement, adding that Rozhkov was also questioned about his "correspondence related to journalistic activities."
