If a US president is impeached found guilty of obstruction of justice and remove from office what would the sentence be for him?

If a U.S. president is impeached, found guilty of obstruction of justice, and removed from office, there is no criminal sentence automatically imposed by the impeachment process itself. Impeachment is a political process conducted by Congress, resulting in removal from office but not a criminal conviction. However, the individual could still face criminal charges in a court of law after leaving office, where potential penalties would be determined based on applicable laws.
