So, if I'm understanding this, the question is if Ted Cruz's name is on a list of clients of a DC hooker or not.
I'm thinking there's a couple of issues that should be considered to evaluate whether this is even relevant.
1) Anyone can make a list and put anyone else's name on it.
2) She(?) is a hooker. Doesn't make her a liar, but... just saying.
3) Oops, sorry about #2 there. She's a DC hooker. That means she's definitely a liar, or in Congress, but I repeat myself.
