"The line where Fox News ends and where Trump begins is getting blurrier by the day," he said on CNN's "Reliable Sources."

"Sometimes via TV, sometimes on the phone, sometimes in person," he said.

"His addiction to Fox and to other pro-Trump commentators leads to impulsive actions."

Stelter said when Trump relies on what he hears on Fox News, he often ends up catching his staff off guard and forcing them to scramble to "make it look like he knows what he's doing."

He traced Trump's plan to send National Guard troops to the U.S.-Mexico border to segments Trump had seen on Fox.

Trump, who often rails on other media networks and reporters, is known to frequently watch Fox News.

He often tweets out stories he hears on the network and reportedly speaks to some hosts on the network on the phone or in person.
