Journalist George Stephanopoulos, who interviewed Joe Biden following a presidential debate that raised red flags about his health, doesn’t think Biden can make it another term as president.

In a video shared with entertainment news outlet TMZ, a passerby spots Stephanopoulos walking on the street, wearing headphones and looking at his cellphone in New York. The person approaches Stephanopoulos and asks him how he is doing. The camera is pointed downwards during the exchange.

“What do you think? Do you think Biden should step down? You’ve talked to him more than anyone else has lately,” says the passerby. “You can be honest.”

“I don’t think he can serve four more years,” a voice that reportedly belongs to Stephanopoulos replies, off camera.
