1) I'd then add the word "Social" before "Fraternity men who" to reflect the way the list is structured.

2) Using NIC is just fine here, I believe. The only groups to leave the NIC other than by merger, as far as I know were those that formed the FLA, and with the changes to that, the only group no longer in the NIC is Kappa Sigma, which doesn't affect the list.

3) DDE became an honorary member of TEPhi during his time in office according to the TEPhi wikipedia article.

4) Having been involved in working with the offering of Honorary membership, saying that a President was given honorary membership says little in regards to the Leadership opportunities in GLO that the list is apparently supposed to show.

5) And as such, membership in Alpha Phi Omega as a student would show more in that regard than accepting membership in a Social Fraternity years *after* being president.

I don't think that Phi Delta Theta has rejoined the NIC.

Ah, when I looked at the FLA article, I missed that while Phi Delta Theta had left at the same time those who joined the FLA did so, they didn't join the FLA. But I don't know if that effects Benj. Harrison given that he is listed with Phi Delta Theta and Delta Chi. (Though Delta Chi was a law fraternity at the time and didn't disallow dual membership until 1909)

I also compiled a Vice Presidents list. wp.me/p20I1i-11G

I believe it should also be noted that President Clinton is a brother of Kappa Kappa Psi National Honorary Band Fraternity.

Like the Brothel Laws?

One of my friends was a TKE in the 1980's at Ohio State. When President Reagan was campaigning (fall 1984) in Columbus, Ohio, he stopped by the TKE house (his fraternity) to shake hands and meet the brothers. He also bought the chapter a couple of kegs. (I don't think that last part would be okay anymore.)
