Fox News host Chris Wallace called out presumptive Democratic nominee Joe Biden on Sunday for turning down an interview. The challenge issued by Wallace arrives a week after President Donald Trump sat down with Wallace in what was at times a contentious interview.

"In our interview last week with President Trump, he questioned whether his Democratic opponent Joe Biden could handle a similar encounter," said Wallace at the end of his "Fox News Sunday" show. "Well this week we asked the Biden campaign for an interview, and they said the former vice president was not available."

President Trump retweeted a video clip of Wallace announcing that the Biden campaign rejected his interview invitation.
