Donald Trump says he "would have no problem" asking Congress to declare war on ISIS, the presumptive Republican presidential nominee told Fox News' Bill O'Reilly.
"It wouldn’t bother me at all doing that," Trump told O'Reilly iun the interview, which aired on May 23. "We probably should have done that in the first place."
While a formal declaration of war would help the effort to combat ISIS, Trump said he also understands the group is not a conventional enemy, despite its ambitions of statehood.
"Look, we are at war with these people and they don't wear uniforms," Trump told the Fox News host, reports Daily Mail. "It's not your traditional war where it's a war against Germany, Japan, whoever."
The former reality TV star also touched on his earlier call to temporarily ban Muslim refugees from entering the U.S. Doing so, he said, presents a security risk to the country, opening the door to another act of domestic terrorism.
"This is a war against people who are vicious, violent people that we have no idea who they are, where they come from," Trump said. "We are allowing tens of thousands of them into our country now so on top of wars on foreign land wait 'til you see what happens in the future. It's probably not going to be pretty."
Democratic front-runner Hillary Clinton has yet to respond to the Republican's tough talk on ISIS. On May 23, for the first time, aggregated national polls showed Trump had pulled ahead of Clinton, leading many to speculate the race for president could be much tighter than anticipated.
Clinton continued to fend off attacks from her own party, declining to participate in a Fox News debate against fellow Democrat and Vermont Sen. Bernie Sanders, according to CNN.
"As we have said previously, we plan to compete hard in the remaining primary states, particularly California, while turning our attention to the threat a Donald Trump presidency poses," Jennifer Palmieri, Clinton's spokeswoman, told CNN. "We believe that Hillary Clinton's time is best spent campaigning and meeting directly with voters across California and preparing for a general election campaign that will ensure the White House remains in Democratic hands."
