Experienced politicians taking time, putting out second press briefing? (9)
I believe the answer is:
statement
'briefing?' is the definition.
(thesaurus)
I can't explain the remainder of the clue.
Can you help me to learn more?
(Other definitions for statement that I've seen before include "Declaration of facts" , "Formal (court) account" , "Announcement, issued by the bank say" , "may be taken by police" , "Formal account given to police" .)
