You must have your real passport with you anyway, because if you are a US
citizen (even if you are also a citizen of some other country) holding a
US
passport it is illegal to enter the US by showing any other passport.

"Real" passport. Irish passports are real passports, too. You're
correct that the holder must have a US passport in order to return to
the US, but you could have probably used a better word other than
"real".
And I guess the o.p is to be regarded as an Irishman and Irish citizen as
well as an American.
As I can see some people here seem to regard the Irish citizenship as a
secondary thing.
