Not only did they visit the USS George Washington, he and his staff stayed overnight and CLEANED OUT the staterooms of "souveniers" like bathrobes, towels, etc.
There is a White House memo floating around telling those who took stuff to send a check to the GW to reimburse them for the stuff they took.
I'm pretty sure that was the Theodore Roosevelt.
In additioned to the aforementioned comments, the letter to the WhiteHouse also pointed out that some of what was stolen were personal items.
