On the heels of a Bernie Sanders/Donald Trump debate being scuttled, Real Time host Bill Maher asked the Vermont senator to discuss how he would approach countering the Republican candidate’s rhetoric.

“I’ve been trying to get this answer out of everybody who comes on this show: what is the right strategy to run against Donald Trump?” Maher asked. “Obviously Hillary Clinton doesn’t have it. What would be your strategy?”

“That is a good question, and I would not be honest if I told you I’ve figured it out yet,” Sanders replied. “He is so unpredictable because he lies all of the time — not a joke. He changes his mind all the time.”

The Democratic candidate pointed out that Trump was willing to debate him as recently as Thursday — provided the event raised $10 million for charity — only to back out a day later after a tech company met the real estate mogul’s condition.

“How do you deal with that?” Sanders asked.

“More importantly, he’s not held accountable on that as other politicians are,” Maher replied.
