In May 2024 Marine Le Pen and the French National Rally refused to sit with the German AfD in the European parliament. The AfD were too extreme for them and embroiled in a series of scandals where their leaders were sanitising the Nazi era.

She called for a 'cordon sanitaire' between the parties.

Elon Musk doesn't have the same concerns as Le Pen. In fact he is not only not concerned, he is admiring and totally supportive.
