France has summoned the American ambassador to Paris after the diplomat, Charles Kushner, wrote a letter to French President Emmanuel Macron alleging the country did not do enough to combat antisemitism.

France will summon U.S. Ambassador Charles Kushner to its foreign ministry on Monday after the American diplomat levied sharp allegations against his host country over its “lack of sufficient action” in response to the rise of antisemitism.

France issued an unusual rebuke to US Ambassador Charles Kushner and said he’ll be summoned to the foreign ministry, after President Donald Trump’s envoy to Paris accused French authorities of being lax on antisemitism.
