"Some excesses make your stomach turn, even in the United States, especially when as did Donald Trump he speaks ill of a soldier, of the memory of a soldier," Hollande said at a meeting yesterday with members of the French Presidential Press Association.
Hollande was referring to Trump's recent comments about Capt Humayun Khan, a US Muslim soldier killed in Iraq in 2004.
Government spokesman Stephane Le Foll said Hollande's comments were a response to Trump's recent verbal attacks on France.
Last month, Trump said France would be among countries he would subject to the "extreme vetting" he is proposing for those seeking to enter the United States, a move he says is necessary to deter attacks by people coming from countries "compromised by terrorism."

France has been hit by a series of attacks carried out by Islamic extremists since 2015.
Le Foll also said that President Barack Obama was "well qualified" to make comments describing Trump as "unfit" and "woefully unprepared" to serve in the White House.
