President Donald Trump is ready for the fight to keep his seat in the White House.
In the final few minutes of a nearly 45-minute interview Thursday night with Sean Hannity on Fox News, Trump offered his own scouting report on some of the leading 2020 Democratic presidential contenders, though he doubted any of them would be able to take on the challenge of the presidency.
There are currently 20 Democratic candidates, one of the largest and most diverse fields in U.S. history.
Here's what Trump had to say about a few of them:
Trump had one simple message for the former vice president after he officially announced his candidacy early Thursday: "Welcome to the race Sleepy Joe."
The president used the same nickname during Thursday night's interview.
“I think we’re calling him ‘Sleepy Joe,’ ‘cause I’ve known him for a while and he’s a pretty sleepy guy," the president said.

He added that he doesn't believe Biden has the "level of energy and, frankly, intelligence" to deal with foreign leaders such as China President Xi Jinping, who will soon visit the White House.
Trump has previously kicked around other nicknames for the Delaware Democrat, including "Crazy Joe Biden." The president told Hannity that some had advised him to think of a different nickname.
"A lot of people wanted me to change the word 'sleepy' to something else that rhymes with it, does that makes sense to you?," he said. "I thought it was too nasty."
"He’s not going to be able to do the job,” Trump concluded.
In some of his first remarks on the mayor of South Bend, Indiana, Trump offered warm wishes but predicted disappointment.
"Mayor Pete is not going to make it," Trump said, matter-of-factly, before adding: "I hope he would."
Buttigieg, who is openly gay, garnered increased attention during a recent back-and-forth with Vice President Mike Pence, who has, in the past, been criticized by the LGBTQ community for his policy stances.
In the first quarter, Buttigieg raised more than $7 million, exceeding expectations for a candidate without the name recognition of many of his competitors.
"I’m rooting for him, but he’s not going to make it," Trump concluded.
Trump doesn't think the Vermont senator has what it takes, either: “He’s got a lot of energy, but he’s got misguided energy."
Sanders, 77, ran for president in 2016, but lost the Democratic primary to Hillary Clinton, who was then beaten by Trump.
Trump also claimed Sanders has "done very poorly in terms of the Senate."
"He’s had very little legislation," Trump said. "I think he talks a lot, but doesn’t get it done.”
Trump dismissed the former Texas congressman who lost a spirited Senate campaign against Republican Ted Cruz last November.
"He’s fading very fast, I think he’s fading very fast," Trump said. "It looks like he is going to be a thing of the past pretty soon."
While he once looked to be one of the more charismatic potential challengers to Trump, O'Rourke has yet to emerge in the crowded Democratic field.
"He is fading fast," the president repeated. "There is no question about it."
After the California senator announced she was running for president, Trump praised her rollout, saying she had the best "opening act."
Trump wasn't as complimentary on Thursday night.
“I think she’s got a little bit of a nasty wit, but that might be it," Trump said.
That was similar to Trump's past comments about female candidates. During the 2016 election, Trump called Clinton a "nasty woman," sparking a social media movement of Clinton supporters labeling themselves "nasty" women.
