Can people get in trouble for investigating or charging the president?

Question

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?

Answer 1

The policy of the Justice Department is that the President of the United States can not be indicted. https://www.reuters.com/article/us-usa-trump-russia-indictment-explainer/can-a-sitting-us-president-face-criminal-charges-idUSKCN1QF1D3

All federal prosecutors are part of the Justice Department and that means the guidelines for them say it is prohibited. There is not an actual law saying you can or can't indict the president. The idea is that impeachment is the right way to handle presidential wrongdoing, because the president shouldn't be distracted and he could be charged after leaving office or if he was impeached.

The president can be investigated though and some have. https://www.abc.net.au/news/2018-03-13/trump-nixon-five-times-the-fbi-went-up-against-the-president/9539192
