Former White House communications director and press secretary Stephanie Grisham has claimed that the former US president "has no respect" for classified information and would frivolously show off secrets to associates.

Asked on MSNBC's Alex Witt Reports if Trump showed documents to others during private meetings, Grisham said: "The short answer is yes.

"I watched him show, uh, documents to people at Mar-a-Lago on the dining room patio. So, he has no respect for classified information. Never did."

Grisham - who served as former First Lady Melania Trump's chief of staff - also discussed a secret audio tape that surfaced of the maverick politician discussing "secret" plans to attack Iran with a writer, a publisher and two administrative staff members at his Bedminster golf club and says it highlights Trump's fecklessness towards the issue.

She said: "You know, listening to that exchange every time, it just makes me so angry. He talks specifically that he should have declassified it, but he didn't. So there, I think, is proof."

Last month, Trump pleaded not guilty to 37 felony charges relating to his alleged mishandling of classified documents that he took from the White House to his Mar-a-Lago property.
