And Ms Clinton predicted that Mr Trump will immediately announce he is running again in 2024 when he leaves the White House.
“Trump's not going away, he may have to finally have to leave the White House, but he's going to turn around the next day and say he's running for president again,' said Ms Clinton on actor Dax Shepard’s podcast.
“And then he's going to be out there, he's going to have rallies, because it's like lifeblood to him.
“He's probably going to be owning some kind of media outlet where he's going to be peddling his stuff everyday.
“Somehow we've got to break through the noise.”
Ms Clinton also praised Joe Biden’s “fabulous policies” and urged Democrats to better promote them.
“We've got to figure out how to translate that, and everything he wants to do, into a narrative that captures those eyeballs,” she said.
The former presidential nominee also admitted he difficulty she had dealt with following her 2016 loss to Mr Trump.
“One of the most difficult transitions I've ever had to go through was unexpectedly not becoming president, because I thought I was on the path to becoming president, I had a very clear idea of what I wanted to do," she said.
“I really felt the weight of history, the weight of expectation the thousands of girls and young women who showed up at my events.”
Ms Clinton told Mr Shepard that despite her loss she did not hold any grudges towards Kamala Harris for becoming vice president.
“I'm very personally attached to her and invested in her success,' said Ms Clinton.
“I always believe that we're in a relay race. Let’s keep opening up the pipeline, not just women, but people of colour, LGBTQ.”
She also gave parenting advice to Mr Shepard, who has daughters aged five and seven with actress Kristen Bell.
And she admitted she had found it difficult “constantly trying to find the right balance” when raising daughter Chelsea Clinton.
“Not imposing on her what I wanted her to become, but trying the best I could to enable her to become whoever she was going to be,' said Ms Clinton.
'You know, it's hard. I mean, it's the hardest job I ever had.”
