Steven Cheung, an assistant to President Donald Trump, complained after CNN allegedly declined to interview White House adviser Stephen Miller.

"Stephen Miller has graciously made himself available to appear on any CNN show these last few days to discuss a wide range of topics and to push back on fake news," Cheung fumed on Wednesday. "Yet, CNN is so afraid they declined to have him on, probably because they know he'd run circles around any of their hosts."

"CNN is actively engaging in partisan politics and acting as the propaganda arm of the Democrat party," he added.

Miller is known for his inflammatory rhetoric about immigrants.
