French President Emmanuel Macron said on Tuesday his phone calls with U.S. President Donald Trump and other world leaders are like sausages — it's better not to reveal the contents.

During a news conference with Israeli Prime Minister Benjamin Netanyahu, Macron was asked about a CNN report on Monday saying that a phone call between him and Trump last week had been "terrible."

Borrowing a quote from the 19th-century Prussian statesman Otto von Bismarck, Macron summed up his policy of refraining from making off-the-record comments about his conversations with other world leaders.
