The production company behind the American version of the Russian state-funded network RT laid off most of its staff on Thursday, according to a memo obtained by CNN.

Misha Solodovnikov, the general manager of the production company, T&R Productions, told staff that it will be “ceasing production” at all of its locations “as a result of unforeseen business interruption events.”

“Unfortunately, we anticipate this layoff will be permanent, meaning that this will result in the permanent separation from employment of most T&R employees at all locations,” Solodovnikov wrote in his memo to employees.
