Washington (CNN) Donald Trump said Sunday that Russian President Vladimir Putin won't make a military move into Ukraine -- even though Putin already has done just that, seizing the country's Crimean Peninsula. "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 on Sunday with ABC's George Stephanopoulos on "This Week." "Well, he's already there, isn't he?" Stephanopoulos responded, in a reference to Crimea, which Putin took from Ukraine in early 2014.
