Fox News chief political analyst Brit Hume said America is in an "age of exaggeration" after the Denver Post published a letter to the editor from a Trump critic who accused him of treason and made reference to the execution of traitors.

Post reader Suzanne Gagnon of Lakewood, Colo., criticized President Trump's summit with Russian leader Vladimir Putin.

"If it walks like a traitor, and talks like a traitor, and acts like a traitor … it is a traitor. Ethel and Julius Rosenberg were executed on a basis of far less evidence than is had on Trump and many in his administration," Gagnon wrote, adding that "I believe there are many more actions that can and should be taken against Trump to keep him from destroying the U.S."

Hume said that the letter is an example of "everybody... go[ing] to DEFCON-1 over everything."

He added that former top officials like former CIA Director John Brennan have accused Trump of treason on national television.

"On the other side, everybody is said to be corrupt. There's no reasoned discussion going on right now," he added.
