good evening. donald trump has called women names, he's criticized a female opponent's face, and he said that women who were to get illegal abortions should be punished. he took that last comment back. but it has not mitigated the tsunami of outrage against him. so why then are two female youtube personalities going so far out of their way to stick up for trump? my "nightline" coanchor byron pitts with a fascinating account tonight. >> she will make an unbelievable first lady. >> reporter: tonight melania trump making a rare appearance on the campaign trail of wisconsin for her husband. >> no matter who you are, a man or a woman, he treats everyone equal. >> reporter: perhaps in an attempt to rally women around the candidate who by most measures is having trouble with the ladies these days. >> nobody has greater respect for women than donald trump.

i struggle with bipolar depression, and it's hard. i miss out on life's little moments. so i talked to my doctor and he prescribed latuda. there are many forms of depression. latuda is fda approved to treat bipolar depression, which is different from other types of depression. in clinical studies, once-a-day latuda was proven effective for many people struggling with bipolar depression. latuda is not for everyone. call your doctor about unusual mood changes, behaviors, or suicidal thoughts. antidepressants can increase these in children, teens, and young adults. elderly dementia patients on latuda have an increased risk of death or stroke. call your doctor about fever, stiff muscles and confusion, as these may be signs of a life-threatening reaction, or if you have uncontrollable muscle movements, as these may be permanent. high blood sugar has been seen with latuda and medicines like it, and in extreme cases can lead to coma or death.

which can be fatal, dizziness on standing, seizures, increased cholesterol, weight or prolactin, trouble swallowing and impaired judgment. avoid grapefruit and grapefruit juice. use caution before driving or operating machinery. i spend time with my family just doing everyday things, really. but you know what? they feel pretty special to me. ask your doctor if once-daily latuda is right for you.
