(CNN) President Donald Trump called Joe Biden "weak" and said he is not worried about a potential challenge from the former vice president in the 2020 presidential race, during a phone interview with Fox News' Jeanine Pirro Saturday night. Biden, who served as a senator before becoming vice president for President Barack Obama, is one of many Democrats eyeing a presidential run in 2020. "I think I'm the most qualified person in the country to be president," Biden said during a book tour event at the University of Montana in December. Trump mocked Biden as a "1-percenter," in the interview with Pirro. "And then, Obama came along and took him off the trash heap, and he became the vice president."
