The O'Reilly Factor type TV Show network Fox News Channel genre Talk Show

In a more than 7-minute interview, presumptive Democratic presidential nominee Hillary Clinton made her return to Fox News’ The O’Reilly Factor, her first since the 2008 Democratic Primary. Speaking with host Bill O’Reilly via telephone, the former U.S. Secretary of State called in to discuss Thursday’s attack in Nice, France where terrorists drove a tractor-trailer through a crowd celebrating Bastille Day, killing at least 77 people.

Before Clinton’s interview, presumptive Republican nominee Donald Trump called into the show as well.

“It’s terrible that France has faced too much tragedy and violence,” Clinton began with O’Reilly, “and we need to stand strongly with them, because events like this remind us how vital it is in every way not to abandon them.”

“We’ve got to do more to understand that this is a war against these terrorist groups — these radical jihadist groups; it’s a different kind of war,” she continued, addressing the host’s question about approaching ISIS as a World War III situation. “We need to be smart about how we wage it, but we have to be determined that we’re going to win it.”

Clinton called for better intelligence cooperation and “tough diplomacy” between agencies in the U.S. and those in other countries, “starting with our friends.” She also said that sending in more ground troops is exactly what ISIS wants from its enemies. “We have to go after their headquarters, we have to keep pushing them into a smaller and smaller territory so that we can take out their leadership, take out their infrastructure,” Clinton explained.

Trump earlier answered similar questions posed by O’Reilly, including whether or not he thinks “we’re in a world war scenario.” “I certainly do, and I’ve been saying it for a long time, and it’s out of control,” Trump said, calling for “strong leadership.”

Asked whether he would mobilize NATO and commit ground and air forces, Trump said, “I would say that would be just fine, and I’ve been saying it. … We’re supporting NATO, and we should at least get something out of it.”

Trump also spoke out against immigrants, including Syrian refugees (the majority of which are children, O’Reilly pointed out), saying he considers them security threats. “You really can’t tell where they come from. They may be ISIS,” Trump said. “This could be the great Trojan horse of all time.”
