You might've seen it trending on Facebook.

Matt Lauer is facing criticism after he asked General Motor's CEO Mary Barra about balancing her work life and her role as a mother.

Dozens of people took to Twitter - saying their disappointed in him for his sexist line of questioning.

He referenced another interview she'd given where she said her kids would only hold her accountable for one job.

Lauer then asked if she thought she could fulfill both roles well.

She said that she has a great team, and the support of her kids, so she thinks she can.

But - some people say that he never would have asked a man about being a father and a CEO at the same time.

Lauer has responded to the criticism with this statement:

As part of the interview, I referenced this Forbes article (http://www.forbes.com/sites/joannmuller/2014/05/28/exclusive-inside-mary-barras-urgent-mission-to-fix-gm/) where Barra talked about the challenge of balancing work life and home life. She said, “My kids told me the one job they are going to hold me accountable for is mom.” She had just accepted the job as the first female CEO of a major American automotive company, and in the article she said that she felt horrible when she missed her son’s junior prom. It’s an issue almost any parent including myself can relate to. If a man had publicly said something similar after accepting a high-level job, I would have asked him exactly the same thing. A couple weeks ago, we did a series on “Modern Dads” and the challenges of fatherhood today. Work-life balance was one of our focuses. It’s an important topic, one that I’m familiar with personally, and I hope we can continue the discussion..
