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 strongly rejected the “unacceptable” allegations in Kushner’s letter, which the ministry said “fall short of the quality of the transatlantic relationship” between the US and France.

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.
