"When the problem of lying is at the point where the person is unable to control it, that person is considered to be a pathological liar.” (www.addiction.lovetoknow.com). A pathological liar believes the lies they tell and may not be rooted in reality. They lie about every aspect of their life and every lie has a meaning positioned for their gain."

Certainly, everyone - including you - lies on occasion. To attempt to conflate that with what Trump does is a patently false equivalence. 

Susan Rice is not a pathological liar. Trump is. I would classify him as a sociopath. 
There is a world of difference between unknowingly making what is ultimately determined to be an untrue statement - as Rice did - because you relied upon incorrect facts and willfully, deliberately lying, which is what Trump and Conway do all day, every day.  Especially Conway, because she has more control than Trump does.
