In an interview with LTV's Ilze Nagla in Brussels, Grigule, who is from the same Greens and Farmers Union party as Prime Minister Maris Kucinskis, defended herself without attempting to explain the reasons for her vote, despite the passage of two months.
Asked directly if she did not have a duty to justify her votes to the society that sent her to Brussels, Grigule replied:
"There's a proper time for explaining... there's a time when you should clarify things and there's a time when you should not clarify things. When everyone's running around crying there's no point clarifying things as you won't be heard," the MEP said, in passing up the opportunity to be heard very clearly on national television.
She did however say she had produced an article on the matter for an unnamed media outlet which would be printed before the end of January.
"But I can't tell you with 100% certainty what the publisher's plans are," Grigule said.
She also said Prime Minister Maris Kucinskis, who initially raised questions about her continued participation as a member of ZZS, should "think three times" before expressing such ideas.
She was for a while allied with the anti-EU British UKIP party in the European Pariament but is now allied with the Alliance of Liberals and Democrats.
She is also known for campaigning against Latvia's adoption of the euro.
As previously reported by LSM, in late November Grigule voted against an EP motion condemning the use of propaganda and misinformation by both Russia and terror group Daesh.
However, Grigule has faced no disciplinary measures as a result of the vote as yet.
During the interview she also shrugged off suggestions there was anything wrong with a member of her family working in Brussels for MEP Andrejs Mamikins of the rival Saskanas party while a member of his family works in her bureau.
Mamikins also voted not to condemn Russia and recently popped up in Syria alongside Russian politicians shaking hands with President Assad.
According to European Parliament records, Grigule last asked an individual question in the parliament on 12 November 2015.
Since then she has signed up to one joint question (along with dozens of other MEPs) in 2016 and one in 2017. She last gave a speech in a plenary session of the parliament on February 9, 2015, nearly two years ago.
