Bill O’Reilly showed rare admiration for former president Barack ObamaTaylor Swift.

The former Fox News star gave his insight on former US presidents for an upcoming special on NewsNation titled Bill O’Reilly’s Confronting the Presidents: America’s Best and Worst.

He revealed that Teddy Roosevelt was the ‘Taylor Swift of masculine men,’ because ‘Wherever he went the crowds loved him.’

When asked to clarify, O’Reilly added: ‘Highest energy president by far; Teddy Roosevelt.’

O’Reilly also discussed his views on Obama, saying:  ‘I didn’t think he was damaging the country at all. Obama is the hardest working modern President.

‘And that’s why I didn’t like Biden. Obama didn’t like Biden because Biden was like taking a nap every three hours.’

He added: ‘I don’t think Obama was a bad president at all. In fact, you could put him in the good category because he uplifted a portion of the population that needed to be uplifted, people of color.’

O’Reilly claimed he had a good relationship with the 44th president, but still included criticism of the Democrat in his analysis, including what he called his mass spending tactics.’

In a clip provided exclusively to DailyMail.com O’Reilly also discussed Joe Biden’s legacy as he denied that he is the ‘worst president.’

‘Not even close,’ the presidential historian said while adding that he has pressing questions about Biden’s immigration policies.

O’Reilly said: ‘I’d like to know who made that open border executive order, that’s what I would like to know.  Did you not anticipate what was going to happen?

‘There has never been an explanation, ever, by Biden of anybody else. Why did you do it? I think as history unfolds, we will find out, but we don’t know now.’

O’Reilly’s NewsNation special premieres on Sunday, September 15.

The pundit previously revealed his thoughts on the 2024 presidential election during his return to the The Daily Show.

The self-described ‘independent’ said there’s only one thing keeping Donald Trump from beating Joe Biden by 25 points.

The commentator, who has been friendly with Trump over the years, says that Trump’s reaction to January 6 ‘has haunted him every day since’.
