Apples, oranges.
RT like most outlets today have different types of programming: news, entertainment, documentary / investigative journalism, talk shows, etc.
RT news has been criticized at times for having a pro-Russia bias, and we've seen high-profile resignations in the past from journalists accusing RT of censorship.
But that's just one part of RT. As a whole RT has journalists & correspondents doing good work. During the Ukraine crisis Abby Martin famously condemned Russia's action on air. Larry King and Jesse Ventura currently host shows on RT and they're hardly fans of Putin.
Evaluate Ms. Slier on her previous work to see if she's the person to talk to or not.
