It has emerged EU Trade Commissioner Phil Hogan visited Kildare again before returning to Brussels.
A spokesperson says it was not in breach of Covid-19 regulations as he was in Kildare to collect his belongings.
The latest revelation in Mr Hogan's movements before and after the Oireachtas golf society dinner follows European Commission (EC) President Ursula Von der Leyen's request for more information from the under-fire Trade Commissioner.
Yesterday, a spokeswoman for the EC president said Mr Hogan, the EU's trade commissioner, had given an account of his actions to the president, but she had requested further clarification from him.
European Commission spokeswoman Dana Spinant told reporters: "This is a matter which requires careful assessment on our side.
"It is a matter where details count, therefore the president has requested Commissioner Hogan to provide a full report covering the matters ... the president has received such a report from Commissioner Hogan last night."
She added: "The president has requested further clarifications because details are important, and she wishes to have them."
Ms Spinant said there were "moral aspects" involved in the need to follow coronavirus rules, as well as legal ones.
The Irish Independent reported Mr Hogan stayed in the lockdown county the night before he went back to the Belgian capital.
Public outrage has been sustained since the Irish Examiner revealed more than 80 people attended an Oireachtas golf dinner in Galway, the day after new measures were put in place by the government restricting such gatherings to just six people.
The EU Commissioner Phil Hogan came under sustained criticism for his presence at the society dinner with both the Taoiseach and the Tánaiste urging him to consider his position last weekend.
