Fox News senior judicial analyst Andrew Napolitano said Monday that President Trump’s “foul language” and “dog whistles of lawless behavior to many of his supporters” call into question “the president’s fitness for office.”

“He publicly calls people crude names, uses foul language, and sends dog whistles of lawless behavior to many of his supporters,” said Napoltano on “Liberty File” on Fox Nation, the network’s streaming service that launched one year ago. “All of that is a question of free speech, personal taste and political risk.”

“But threats to ignore parts of the Constitution are not matters of speech, taste or risk,” the former judge continued. “They reveal character traits but question the president’s fitness for office.”
