CNN's Ana Navarro blasted President TrumpDonald John TrumpDems flip Wisconsin state Senate seat Sessions: 'We should be like Canada' in how we take in immigrants GOP rep: 'Sheet metal and garbage' everywhere in Haiti MORE on Friday over his handling of North Korea, saying "it's like he's playing Battleship in between golf games." 

"I think one of the things that gives me some comfort level is the idea that he's got very strong, very measured combat veterans like John Kelly, like Mattis around him, who hopefully are taking a serious look at this," she said, referring to the White House chief of staff and Defense Secretary James MattisJames Norman MattisOvernight Defense: GOP chair blames Dems for defense budget holdup | FDA, Pentagon to speed approval of battlefield drugs | Mattis calls North Korea situation 'sobering' Mattis: North Korea situation 'sobering' Trump administration withholds million from UN agency for Palestinians MORE

"Donald Trump has no idea what he's doing," continued Navarro, who supported former Florida Gov. Jeb Bush during last year's Republican presidential primaries and frequently has harsh criticism for Trump.

"Let's not even pretend that he does. This is a guy who went to military school and thinks that makes him a military expert. As far as I'm concerned, it's like he's playing Battleship in between golf games at his golf course."

"But he does. He did have the wherewithal of getting some very seasoned combat veterans, who do understand the world around him, and hopefully they will have an influence on what's happening," she said. 

Trump earlier this week said North Korea "will be met with fire and fury ... like the world has never seen" if it continued to threaten the U.S. On Thursday, he said that statement might not have been strong enough.
