JD Vance’s team had the army corps of engineers take the unusual step of changing the outflow of a lake in Ohio to accommodate a recent boating excursion on a family holiday, the Guardian has learned.

The request from the US Secret Service was made to “support safe navigation” of the US vice-president’s security detail for an August outing on the Little Miami River, according to a statement by the US army corps of engineers (USACE).

Vance was spotted in the south-western Ohio area on 2 August, his 41st birthday, according to social media posts that noted he was seen canoeing on the river, a tributary that Caesar Creek Lake feeds into.
