An influential Iowa political activist is calling on President Trump to fire Anthony Scaramucci after the White House communications director went on a profanity-laced tirade during an interview with The New Yorker.

"'Silence equals assent.' @POTUS must model and demand a higher standard. @Scarramuci should be fired immediately," Bob Vander Plaats, the president of conservative group the Family Leader, tweeted Saturday.

In a separate blog post on the Family Leader's website, Vander Plaats urged Trump to wash "Scaramucci's mouth with a bar of soap" and promptly oust him from the White House.

"Mr. President, it is time to look in the mirror, accept responsibility, apologize to the American people, and declare an end to this behavior immediately," he wrote. "While what I’m urging may not be the 'Trump' brand, it is the brand of a leader. We need a leader. You must lead!"

"I suggest you lead by first washing out Mr. Scaramucci’s mouth with a bar of soap," he continued. "After a thorough rinsing, strip his credentials and escort him personally off the White House grounds."

In a conversation with The New Yorker's Ryan Lizza on Wednesday, Scaramucci called former White House chief of staff Reince Priebus a "f---ing paranoid schizophrenic."

Vander Plaats sparred with Trump ahead of the 2016 Iowa Republican caucuses after the conservative activist formally endorsed Sen.

That prompted Trump to take to Twitter to rail against Vander Plaats, whom he called a "phony" and a "bad guy."

Vander Plaats responded by tweeting back at the real estate mogul, saying that, while he considered Trump a friend, he was not willing to offer him his endorsement.

Vander Plaats eventually supported the president in the November general election.
