Looking for a media clip

Hey all

For my Apollo website www.project-apollo.info (in Dutch language) I am
searching for a sound or movie clip of pres. Nixon when he welcomes the
Apollo 13 crew back on earth.
He says, with Lovell, Haise and Swigert standing by his side: "Theirs is the
spirit that build America"
I've seen this part on Tv so I know it exist but haven't been able to find
it on the web.

Anyone an idea where to look?

Grtzzz and thanks in advance
