"If I could make one national security recommendation to the president it would be stop watching Judge Napolitano on Fox," Schiff said on CNN, referring to Andrew Napolitano, a Fox News analyst.

"This may be the only time where the country would benefit from a national security point of view if the president of the United States were watching cartoons in the morning instead of something else," Schiff added.

Schiff said a Thursday morning tweet from Trump almost "doomed" a key House vote to renew the National Security Agency’s warrantless surveillance program.

The president wrote on the social media site that the provision of the Foreign Intelligence Surveillance Act known as Section 702 was potentially used to justify alleged government surveillance of his presidential campaign.

The comment appeared to be at odds with the White House's official position, which was supportive of the measure.

Trump soon followed up with another tweet calling on lawmakers to reauthorize the program. But the tweets stirred confusion among lawmakers, including Schiff.

"Earlier this morning when those tweets started coming in, I also asked that we hold off [on voting on the bill] because it created so much of a cloud of uncertainty about — among other things — what was the administration's position on this bill," Schiff said on CNN.

Many have observed a connection between topics discussed on Fox News and Trump's early morning tweets. He has previously praised "Fox and Friends," the network's morning show.
