President Donald Trump and White House aides are reportedly frustrated with the chief of staff, Mick Mulvaney, over not having a response plan for Trump's recent call with the Ukrainian president that has spurred calls for his impeachment.

The White House released a memo of the call on September 25, which immediately ignited outrage against Trump for pressing a foreign leader to investigate Trump's political rival.

White House press secretary Stephanie Grisham dismissed CNN's story about Mulvaney on Saturday, calling it "manufactured palace intrigue."

"The fact is that President Trump and this Administration have done nothing wrong," Grisham said in a statement. "Why would we need to implement a strategy to explain the contents of a document we willingly released? Sounds to me like more anonymous troublemakers working to stir the pot for their own selfish reasons."

A senior Mulvaney adviser also denied CNN's report, telling the network the story "literally has no basis in reality."
