Oh, you’re referencing Dr. Phil McGraw?  I’m aware of some recent controversies, although not all of them were really a big deal.  He’s had a long career as a TV personality. He has a long history in treating addiction and substance abuse, and some critics say he exaggerates for effect. He’s known for telling stories that are entertaining and emotional.

I can give you some information on his controversies and legal problems. His Wikipedia entry was just updated a couple of weeks ago and some of the text is included here for you.  Does this sound helpful?
