President Trump said he would release his tax returns, but he hasn't yet. Why should he allow himself to be interviewed on Russian collusion, when there is no proof that it occurred, and the more Congressional committees release to the public, the more this is proven. So why be interviewed and be tricked into a perjury charge because someone else said something that conflicts with what President Trump might say. President Trump has won, why give Democrats something else to charge him with when they can't prove their original false accusations?
