Treason! Arrest him! The Democratic lawmaker who enrages Donald Trump

For nearly three years, President Donald Trump has dismissed the investigations that have shadowed almost every day of his presidency as hoaxes and witch-hunts, and the people leading them as crooks and liars. The Democratic lawmaker, chairman of the House Intelligence Committee, has become the public face of a rapidly escalating impeachment inquiry that is the latest and perhaps most serious threat to Trump’s presidency. Trump, who has branded the impeachment probe a "hoax," has attacked Schiff as a "lowlife" and a liar, thundered at him during a White House news conference and suggested that he be questioned or arrested for treason.
