The leader of France's National Rally said police seized documents from the far-right party's headquarters Wednesday, a raid prosecutors said was linked to a French probe into alleged illegal campaign financing.

Prosecutors said they are investigating allegations of illegal financing of longtime party leader Marine Le Pen’s 2022 presidential bid, and the party's European Parliament and French parliamentary campaigns.

Investigations around potentially misused funds are piling up for presidential hopeful Marine Le Pen and her party. Leaders are framing the moves as a witch hunt.
