Sen. J.D. Vance (R-OH) got into a contentious disagreement in an interview on Sunday over former President Donald Trump calling for an investigation into President Joe Biden.

Vance criticized the media and Democratic lawmakers for how they have “lost their minds” over Trump saying he would “appoint a real special prosecutor to go after” Biden and his family. The Ohio senator argued that Trump was talking about investigating Biden for “wrongdoing” and that the current president has already been doing this for several years now.
