A live microphone Tuesday night picked up MSNBC’s Chris Matthews raving about Melania Trump’s appearance after her husband, presumptive presidential nominee Donald Trump, won in Indiana.

“Did you see her walk? Runway walk. My God is that good,” Matthews said, according to Variety. “I could watch that runway show.”

Matthews could be heard in the background during the network’s live coverage as Brian Williams and Rachel Maddow provided analysis on the night’s results.

Williams quickly transitioned to a commercial break after Matthews’ remarks.

In a statement to Variety, a spokesperson for Melania Trump said: “Melania Trump is an accomplished businesswoman and entrepreneur in her own right, achieving tremendous success in a variety of industries, including an illustrious modeling career, as well as being a dedicated wife and mother. 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.”

It’s far from the first time Matthews has made sexist remarks on the air. In 2011, he said rising Alaska Gov. Sarah Palin “could not be hotter as a candidate,” called former Secretary of State Hillary Clinton “witchy” and said she only had a political career because “her husband messed around.”

Variety first reported the remarks.
