Gossip about new chap from Washington DC? (4)

I believe the answer is:

yank

I'm a little stuck... Click here to teach me more about this clue!

'chap from washington dc?' is the definition.
'Yank' can be an answer for 'chap'. I'm unsure of the 'from washington dc?' bit.

'gossip about new' is the wordplay.
'gossip' becomes 'yak'.
'about' indicates putting letters inside.
'new' becomes 'n' (abbreviation as in New Testament NT).
'yak' placed around 'n' is 'YANK'.

Can you help me to learn more?

(Other definitions for yank that I've seen before include "Pull roughly" , "sudden 24D [DRAW] ?" , "Unceremoniously drag" , "Wrench" , "Jerk, pull suddenly" .)

I've seen this clue in The Times.
