The day after suicide bombers killed 41 people and injured hundreds more at a Turkish international airport, Republican Donald Trump doubled down on his calls for techniques like waterboarding while interrogating terrorists.
In addition to the 41 deaths, 239 people were wounded when a trio of attackers started with gunfire at Istanbul's Ataturk airport on June 28, then blew themselves up as police responded, according to the BBC.
Turkish Prime Minister Binali Yildirim said his country's investigators believe the Islamic State was behind the attack, but so far the group has not claimed responsibility.
Trump, who has advocated waterboarding in the past, repeated his call for the "enhanced interrogation technique" at a rally in Ohio.
The Islamic State, Trump said, "can do chopping off heads, drowning people in steel cages, they can do whatever they want to do."
To effectively fight the terrorists, he said, "we have to fight so viciously and violently because we're dealing with violent people."
Republican Sen. John McCain of Arizona criticized Trump during an appearance at Washington's Bipartisan Policy Center. McCain, a Navy pilot, suffered extensive torture at the hands of the north Vietnamese during the Vietnam War. He spent six years in captivity, including two years in solitary confinement.
Torture, McCain said, is "not what we are all about," according to NBC News.
"But perhaps more important than that ... it doesn't work ... Because if you inflict enough pain on someone they will tell you whatever they think you want to hear," the Republican senator said.
