Any Investment Guru's out there?

I remember reading and can't locate an article that talked about
the effects of a credit downgrade on the US.

The article stated that the securities issued when the US has/had
a AAA credit rating will be worth more than those issued if and
when the US rating falls to AA. Like the rating at the time
sticks with the security.

Has anyone else besides myself ever heard this?

1. In theory yes but in actual market pricing you'll find they don't care the issue date n/t
