GREY'S Anatomy star Ellen Pompeo has revealed why the controversial human trafficking and child migrant are her favourite story lines.
The actress has played lead character Meredith Grey on the long-running series since 2005 and discussed the show's gripping story lines during an Instagram Live with Variety.
The 50-year-old said: "One thing that [showrunner] Krista [Vernoff] and I talk a lot about is, as subtly as we can on a network soapy drama, to call out our healthcare system and the problems with it. "We were able to have a storyline that dealt with a young, undocumented child not having health insurance, [and that] was a storyline that Krista and I felt really grateful to be able to tell.
