West Virginia Senator Joe Machin (D) addressed NSA's controversial surveillance program on Sunday.
On CNN's "State Of The Union," Machin said that, "Big Brother is truly watching you."
He also said he believed the NSA could find a balance between keeping the country safe and not invading citizens' privacies.
“I think you’re going to find backing off some, making some changes that are going to keep us secure and safe," he said, according to Politico.
The West Virginia Democrat also addressed gun control. Once a strong NRA ally, Machin has spoken out in support of new gun laws and sponsored a bill to strengthen background checks.
Machin said he was "hopeful" that new gun laws would pass in 2014.
