Watch: JD Vance shows off shamrock socks in meeting with Taoiseach 

As Taoiseach Micheál Martin attended a breakfast with JD Vance to mark St Patrick's Day, the US vice president showed off a pair of shamrock-themed socks.

Mr Vance spoke of how he learned of "sock diplomacy" while he was a senator — the act of gifting socks to fellow senators.
