Watch these YouTube stars interview President Obama

A trifecta of YouTube stars interviewed President Obama in the White House Friday afternoon as a follow-up to his final State of the Union address earlier this week. 

Destin Sandlin, of the SmarterEveryDay channel, Ingrid Nilsen, known as Miss Glamorazzi, and Adande Thorne, who goes by sWooZie, each grilled the President on a range of topics, including women's issues, terrorism, healthcare, and his favorite "Star Wars" movie in front of individual sets that YouTube created for them in the East Room of the White House. 

With more than 12.1 million subscribers combined, the creators were targeting their interviews to their younger, more digitally savvy fans. 

At peak, about 40,000 people were watching the stream live.
