Anything can be backdoored. An agency that wants to do so would probably

I don't know the current state of NSA mathematical research, obviously,
but it used to be THE biggest employer of mathematicians on the planet,
and there was a point when it had a considerable advance in cryptography
to about anybody else.
It's a well-documented story that the NSA suggested changes to the DES
initialisation vector before it became a standard.
Backdoor ? no.
Resistance to differential cryptanalysis ? you bet.
The fun thing about that is that, at that point, differential cryptanalysis
hadn't been invented... and wouldn't be for roughly ten years. For the
general public, that is.
I don't know if they still have this kind of advance. Probably less.
Good luck verifying the mathematics yourself, though.
