Wayne Knight has reprised his role as perhaps one of the most famous fictional mailmen for one important reason — to call out Donald Trump.

Seinfeld‘s Newman blasts Trump’s treatment of the United States Postal Service in a new two-minute ad from the political action committee PACRONYM.

“According to this month old issue of Dr. Roberta Greenburg’s Time magazine subscription, there’s been a systematic premeditated assault on the U.S. mail by President Trump and his so-called postmaster general,” Knight’s Newman says before spitting on the ground. “That guys never even licked a stamp.”

This ad marks the first time that Knight has reprised the goofy role since Seinfeld ended in 1998. “It’s been my studious attempt to let Newman die,” he told Entertainment Weekly. “I’ve been so associated with the character that it became somewhat of a lodestone in my mind.” Still, he decided that bringing the character back could encourage people to believe in the USPS’ ability to deliver mail-in ballots. So, he signed on to do the character when David Mandel, a Seinfeld writer and producer, promised to write the script.

“If we could capture the voice, if we get it funny, and we could get the message out, I felt like it would be disseminated in a way that would reach people, and that was what was important,” the actor said.

“My brothers and sisters and I in blue will do our solemn best to make sure your ballot is delivered as mandated by the U.S. Constitution,” Knight’s Newman promises in the clip while two men in suits start to remove a post box behind him. “Hey! You picked the wrong government employees to mess with!” he shouts as they walk away with the box.
