Frances le pen ordered to undergo psychiatric tests over is tweets

I think there may be some confusion here. Marine Le Pen, the former leader of the French far-right party National Rally (formerly National Front), has indeed been involved in controversies surrounding her tweets and social media posts. However, I couldn't find any information about her being ordered to undergo psychiatric tests specifically due to her tweets.

In 2018, Marine Le Pen was convicted of tweeting images of Islamic State group executions and was given a fine of €30,000 (approximately $33,000 USD). The conviction was related to her sharing of violent and disturbing images on Twitter, which was deemed to be a violation of French hate speech laws.

It's possible that you may be thinking of a different individual or a different incident. If you could provide more context or clarify what you're referring to, I'd be happy to try and help you further.
