Who is De Niro? Is he someone important?

What is the big deal about two guys talking eleven years ago? Did they do something illegal?

Sorry, but I do not see where Trump did anything wrong. Please enlighten me as to what he did illegal. Did free speech become illegal when I was not paying attention? Did Trump say anything like "kill the pigs?" Hillary embraces BLM and what they say about killing COPs. Did Trump say something like that?
