Not word for word and please correct me.
Is there a law like this? If so: Should any criminal investigation or legal action, investigation even a phone call that takes time from the president in office in any criminal investigation can be interpreted and considered a violation of this stature "The US president cannot be prosecuted for any crime while in office"? Unless it is a political offense like espionage is it a crime to use taxpayer money to investigate the president?
