What US Presidents were Italian?

If you are referring to what US Presidents were born in Italy, then your answer is simple; a US President could not have been born in Italy. If a person was born in a country or region not in American control, then they cannot become a President, since in order to be President, you must be born in a US held area.

If you are referring to how many Presidents have Italian heritage in their blood, I believe that the answer is zero. No US President as of right now has had any noticeable Italian lineage.
