During MSNBC's coverage of the Indiana presidential primary, a hot mic caught host Chris Matthews talking about Donald Trump's wife Melania, as she followed her husband to the podium on election night.

“Did you see her walk?” Matthews said “Runway walk. My God is that good.”

“I could watch that runway show,” he added.

Network host Brian Williams quickly cut to a break after Matthews' comments.

A spokesperson for Melania Trump said she is “an accomplished businesswoman and entrepreneur in her own right.” And the spokesperson went on to say, it is “unfortunate to see the continuous inaccuracies and misrepresentations made by the media of Mrs. Trump as anything less than the independently successful woman that she is.”
