There are a number of well known cases where persons working at NSA were
in the pay of or defected to foreign powers.  The people at NSA are
probably of at least average intelligence.  Therefore they must assume
that a few of the people currently working there are in the pay of
others or will defect in the future.  Putting a trap door into an
ecryption algorithm that will be used to protect the highest level
secrets strikes me as pretty stupid.  You have to assume that other
countries are recording your transmissions and keep copies for umpteen
years so if the trap door ever leaked they could read all of your
messages not to mention the cost and effort that would be involved in
replacing all the hardware to protect current and future message.
