Former Democratic presidential nominee Hillary Clinton Hillary Diane Rodham ClintonBiden leads Trump by 36 points nationally among Latinos: poll Democratic super PAC to hit Trump in battleground states over coronavirus deaths Battle lines drawn on precedent in Supreme Court fight MORE slammed President Trump on Saturday, saying his presidency is worse than she expected it would be.

"I really had such deep doubts about his preparation, his temperament, his character, his experience, but he's been even worse than I thought he would be," Clinton told MSNBC's Joy Reid on "AM Joy."

"I tried in my concession speech to make clear that we should all give him the space to be president for every American. That's what we want from our presidents, regardless of our partisan differences, we want to feel like the person in the oval office really cares about and is looking after everybody," she continued.

"And that just hasn't turned out to be the case, starting with our inauguration, which is how I opened the book talking about how excruciating it was to go and what a missed opportunity for him because all he did was reinforce the dark, divisive image of America that he'd been feeding to his supporters."

Clinton's comments come as she promotes her new book "What Happened," which documents her experience during the 2016 presidential campaign and her shocking electoral loss to Trump.

The former Democratic nominee has not shied away from criticizing Trump's policies in the book and in public, recently slamming him for his rhetoric toward North Korea.

Trump has also taken aim at Clinton in recent days, tweeting an edited video of him hitting her with a golf ball and blasting her criticism of his debut speech to the United Nations General Assembly.
