Here's a look at what Donald Trump's national security adviser has said about Islam.

"I don't see Islam as a religion," retired Lt. Gen. Michael Flynn said at an event in San Antonio, Texas.

"It's like cancer. I've gone through cancer in my own life. So it's like cancer. It's like a malignant cancer in this case," Flynn said at an event in Dallas.

Flynn's critics claim he's Islamophobic. And some of the stuff he's tweeted hasn't really helped his case. Although Flynn has clarified some of his comments.

"To clarify for our viewers, you're not afraid of Muslims?" Al Jazeera's Mehdi Hasan asked Flynn in a May 2016 interview.

"No, no. Otherwise you and I'd be wrestling right now," Flynn said.

Flynn also told Politico in an October interview that the extremist sects of Islam are a cancer, specifically not the entire religion.
