What additional disqualification is imposed on someone who has been removed from office after impeachment?

The disqualification imposed on someone who has been removed from office after impeachment is indeed the inability to hold any public office. This consequence is specified in Article I, Section 3 of the U.S. Constitution, which states that individuals who are impeached and subsequently removed from office can also be barred from holding any federal or state office in the future. This provision aims to ensure that individuals who have committed serious offenses while in office cannot return to a position of power, upholding the integrity of public office and accountability to the public.

The other choices do not represent outcomes associated with impeachment. Mandatory community service is not a consequence outlined in the impeachment process; neither is ineligibility for federal grants or life imprisonment. These options do not align with the established legal and constitutional framework governing impeachment and its aftermath.
