When asked how he would handle a possible presidential debate with President Donald Trump during a CNN town hall event Monday, Sen. Bernie Sanders (I-VT) said he would simply “bring a lie detector along and every time he lies, it goes 'beep.'” Sanders, who launched his second campaign for president earlier this month, added that he has honest, conservative friends, and their differences in opinion is “called democracy.” Sanders told moderator Wolf Blitzer that Trump, however, is a “pathological liar” who “has to be exposed.” “This president is the first president in the modern history of our country who is trying to divide our people up based on the color of their skin, the country they were born in, their sexual orientation, their gender, their religion. And that is an outrage,” Sanders said. The Vermont senator did, however, give the president props for how he has handled the summits with North Korean leader Kim Jong Un. “I think nuclear weapons in the hands of a brutal, irresponsible dictator is a bad idea,” Sanders said, adding that Trump's face-to-face meetings are a “good idea” if they result in denuclearization.
