Former White House aide Sebastian Gorka angrily confronted a reporter after the social media summit with President Donald Trump, and it was caught on video.
Gorka, who is known for his belligerent and vehement defense of the president and his policies, is seen stomping up to Brian Karem, the White House correspondent for Playboy Magazine.
He screamed in Karem's face, "you're a punk! You're not a journalist, you're a punk!"
Karem stood his ground and Gorka stomped away, while in the background other members of the event began chanting, "Gorka! Gorka! Gorka!"
New York Times White House correspondent Katie Rogers posted videos of the altercation on her social media account.
In another video posted by Reuters, Gorka appeared to accuse Karem of "threatening" him before he got into his face.
Gorka also took to his Twitter account and reiterated his claim that Karem was a "punk" and claimed that he had challenged him to a fight.
"These people are not journalists," Gorka said.
"They're punks and political saboteurs," he added.
