FACT CHECK: Trump's Approval Ratings

So now the man is claiming that his approval rating is at 71% or at least 69% and no one can find such a poll except maybe around Sean Hannity's dinner table. No one can even find a poll where Trump's approval rating is as high as his disapproval rating. The Huffington Post has more on this but what I'd love to know is if he's saying this because he actually believes it. Are aides telling him what he wants to hear?
