The likely presidential nominees of both parties react to the attack in France.

FOX's Kathleen Maloney reports:

(Donald Trump) Here we go again.

Republican Donald Trump on FOX's "The O'Reilly Factor".

(Donald Trump) This is war. 

Something democrat Hillary Clinton agrees with.

(Hillary Clinton) This is a war against these terrorist groups, the radical jihadist group. 

But Clinton, also on "The O'Reilly Factor", says we need better intelligence and global cooperation to fight terrorism.

(Hillary Clinton) We need to strengthen our alliances and I include NATO in that. 

Trump wants to cut off the flow of Syrian refugees .

(Donald Trump) We're allowing people into our country who we have no idea where they are, where they're from.
