Former Secretary of Defense Donald Rumsfeld is EXPLAINING his TSA pat-down at Chigago's O'Hare airport this week ... chalking the whole thing up to some bionic body parts!
After TMZ posted the photos of Rummy getting his pat-down on Wednesday ... Donald went to his Twitter page (yes, Donald has a TWITTER page!!) and dropped the following statement:
"It takes those of us with two titanium hips and a titanium shoulder a bit longer to get through TSA ..."
Then, Rummy actually LINKED to our TMZ article!!
That's right ... we got a direct line to a guy who used to kick it at the Pentagon!
