Way to preserve old copy for congressional record (3,4)

'congressional record' is the definition.
I don't know anything about this answer so I cannot tell whether this works.

'way to preserve old copy' is the wordplay.
'way' becomes 'st' (abbreviation for street).
'to preserve' indicates putting letters inside.
'old' becomes 'ex' (prefix meaning former or onetime).
'copy' becomes 'ape' (ape can mean to copy or imitate).
'st' going around 'ex' is 'sext'.
'sext'+'ape'='SEX TAPE'

'for' is the link.

Can you help me to learn more?
