Reporter: That's a far cry from his fear-mongering message on the campaign trail, insisting Democrats were behind that caravan of migrants heading north. He tweeted about immigration and the caravan at least 30 times in the weeks before election day. But since then, the number of presidential tweets about immigration? One. And not a word about those 5,900 American troops he deployed to the border. Today, Arizona's Republican senator Jeff flake called it a ploy to win votes. You can't call it anything but a stunt here. Reporter: Secretary of defense Jim Mattis and homeland security secretary kirstjen Nielsen meeting some of those troops on the border today. Hello, soldiers, how are you doing?
