The man is an imbecile.   

From the article:

"He's not going into Ukraine, OK, just so you understand. He's not going to go into Ukraine, all right? You can mark it down. You can put it down. You can take it anywhere you want," Trump said in an interview with ABC's George Stephanopoulos on "This Week."

"Well, he's already there, isn't he?" Stephanoploulos responded, in a reference to Crimea, which Putin took from Ukraine in early 2014.

"I have no relationship with Putin. I have no relationship with Putin," Trump said.

"Just so you understand, he said very nice things about me. But I have no relationship with him. I don't -- I've never met him," said Trump.

But in a November 2015 Republican primary debate, Trump had said of Putin: "I got to know him very well because we were both on '60 Minutes,' we were stablemates."
