In the beginning the Donald said that he would release them after a so called audit is done.  Then in Jan.:

President Trump has no intention of releasing his tax returns, his senior counselor said on Sunday, ruling out a step he had said he would take once an Internal Revenue Service audit was completed.

“The White House response is that he’s not going to release his tax returns,” the counselor, Kellyanne Conway, said in an interview on the ABC program “This Week.”

He is not going to release them which makes him a liar.  He will stop being a liar when he releases them which he isn't going to do.  Prove me wrong.  Until then, I will consider the Donald to be nothing more than a big fat liar.

So try again or are you going to call his buddy nothing but a liar? 

Amazing anyone would still believe that the Donald will release his tax returns.  Stop being so gullible.
