Trump wouldn't say if he's talked to Putin since leaving office

Wildwood Crest - Trump wouldn't say if he's talked to Putin since leaving office but says, 'If I did, it's a smart thing'.
Translation: Of course I did but I'd rather not admit it. However, if they somehow have evidence, here is my fall back answer: It's a smart thing?
And here is my follow up question: If you think that's a smart thing to do, why wouldn't you have done it? Of course he did.
