When confronted with admitting the truth or telling a lie, TrumPutin's path never varies. Lying is his only real option. When he faces acknowledging an unpopular action, he goes for the big lie. Like his dictator role models. 

So, when asked about separating families, he says: 1) Obama started it, 2) he, TrumPutin, stopped it, 3) the Trump regime does not do that, and 4) separating families would really help to solve the problem of welcoming the tired, poor, huddled masses. 

First, Obama did not separate families, except when there was suspicion of domestic violence. Second, TrumPutin instituted family separation as a policy and he thinks separating families is a deterrent. Third, his hatred of Obama is now a certified pathology.

Stephen Miller is a turd, TrumPutin is a moral and ethical scarecrow, and his administration is the largest grouping of incompetents and toadies ever crowded together in one administration.
