(CNSNews.com) - President Donald Trump has "raised concerns" about alleged corruption and political bias on the part of some current and former FBI leaders, Sen. Susan Collins (R-Maine) told FBI Director Christopher Wray at hearing of the Senate Intelligence Committee on Tuesday.

"What is your reaction?" Collins asked Wray.

Well, Senator, I would say that my experience, now six months in with the FBI, has validated all my prior experiences with the FBI, which is that it is the finest group of professionals and public servants I could hope to work for. And every day, many, many, many, many times a day, I am confronted with unbelievable examples of integrity and professionalism and grit. You know, there are 37,000 people in the FBI who do unbelievable things all around the world, and although you would never know it from watching the news, we actually have more than two investigations. And most of them do a lot to keep Americans safe.

A short time later, in response to Sen. Martin Heinrich (D-N.M.), Wray said "no," he has not seen any evidence of inherent political bias within the FBI. He said he encourages his staff "not to get too hung up on what I consider to be the noise on TV and on social media."
