The former Russian press minister died in Washington, DC on November 5, 2015. Following his death, Lesin's family told media that he died from heart attack.
"We believe that as the American investigators have new information, we would like to receive it directly from those people who are obliged to [provide] it, not from the journalists, not from the reports," Zakharova said.
Lesin was born on July 11, 1958. He served as minister for the affairs of the press, broadcasting and mass communications from 1999 to 2004 and as presidential adviser from 2004 to 2009. He was appointed to head Gazprom-Media holding in October 2013 and resigned in January 2015, citing family reasons. Lesin is also widely credited as the creator of international broadcaster RT.
