GREEN BAY, WI (WTAQ) - Questions continue following Sunday's massacre at a gay nightclub in Orlando, which saw at least fifty people killed, including the gunman, and dozens more injured.
29 year old Omar Mateen has been called by ISIS as one of their operatives in the U.S., however the Florida resident was legally allowed to obtain weapons, and was never charged with a crime.
Wisconsin Senator Ron Johnson sits on the U.S. Senate Committee on Homeland Security.
"We can talk about all these things, we can look at other potential solutions, but until we recognize that it's Islamic terror that inspiring this, it's a real and growing threat."
Johnson says taking away or restricting personal freedoms isn't the answer.
"If you want to slaughter somebody, you can choose a number of different methods. I don't want to be putting any ideas in terrorist's heads, but let's face it...the root cause is the ideology."
Johnson says it's easy to second guess decisions not to keep Mateen on a closer security watch after he passed security checks on two seperate occasions.
