Both U.S. Senators from Ohio are weighing in on the government monitoring controversy.
A National Security Agency official got a grilling on Capitol Hill over questions about the NSA's collection of telephone and Internet data.
Senator Rob Portman told reporters Thursday that though the lines between international and domestic terrorism "have blurred", the government needs to be cautious about its surveillance techniques.
"Of course, we should use appropriate tools to defend our country from terrorism," Portman told a conference call. "But we also have to be sure that when the government uses this kind of power, it's done so narrowly, and it's done so to defend the country in a way that specifically defends our freedoms."
Senator Sherrod Brown, on the WAKR Ray Horner Morning Show on Thursday, says he understands the need to protect the country.
"I agree with that, but I also know that sometime power is abused," Brown said, "...when it's secret and not really brought to light."
Both senators say surveillance powers shouldn't be unchecked under any presidential administration.
