House Intelligence Committee member Rep. Jason Crow (D-CO) clashed with Fox News host Will Cain on Wednesday over the Trump administration’s Signal group chat national security leak controversy.

“The difference between your position and mine is that nobody on my side of the aisle is pretending [perfection]. I’m not. I’m certainly not pretending perfection,” said Cain during their debate. “This administration has admitted a mistake.”

Cain then accused Crow of not having “real national security concerns,” and instead seeing the national security leak as a “partisan political opportunity.”

“Will, I have spent my life in service to this country,” Crow shot back. “I have taken the oath of office, which you have never taken by the way, to put my life on the line to defend this country, and I went to war in Iraq, I went to war in Afghanistan twice. I have stood up time and time again to defend this nation and I have seen my friends give their lives for this country, so do not tell me, do not tell me that I don’t have real national security concerns.”

He continued, “Every single night before I go to bed, every night, I ask myself one simple question: am I keeping faith with the men and women who I have a solemn obligation to keep faith? Our sons, our daughters, our brothers, our sisters that we’re asking right now, while we’re sitting here in the comfort of our offices and under the Capitol dome, to go and fight for us. Are we keeping faith for them?”

“I do appreciate your service, something that I have not done,” replied Cain. “I readily acknowledge and I very much appreciate your individual choice to do so and what you’ve done for this country.”

The Fox News host concluded, however, “I do not think it inoculates you from criticism nor this debate, nor in my mind being inconsistent on your principles here in the course of this debate, but I think you can see by the time that I’ve given you here today, this is always a welcome venue for you to come back and have this conversation.”
