Joe Biden is not ruling out running for President in 2020, the former Vice President has said.

"I haven't decided to run," he told Vanity Fair, " but I've decided I'm not going to decide not to run.

"We'll see what happens."

In a separate interview with InStyle Magazine, Mr Biden, who served under Barack Obama, repeated his somewhat confusing take by saying he has not decided to run for president but has also decided he is "not going to decide not to run".

The 74-year-old Democrat said "this moment in American history sort of fits into my wheelhouse and the strengths I have."

He cited his experience with international diplomacy, his personal authenticity and his willingness to work with both parties.

But he said the decision would be hard on his family, telling Vanity Fair: "You don't run by yourself. Your family is totally implicated. They become news; they become fodder."

Mr Biden said he decided not to run for President in 2016 because of grief caused by the death of his son, Beau, from brain cancer the year before.

"No question," he told the magazine. "I had planned on running, and I wasn't running against Hillary or Bernie or anybody else.

"Honest to God, I thought that I was the best suited for the moment to be President."

He denounced President Donald Trump as not only "self-referential and uninformed" but also a threat to the foundations of America.

“This sounds corny, but everything the founders did was to erect institutions that made it more difficult to abuse power," he said.

"That’s why they have three different branches of government. And what really worries me about this administration is the frontal attack on those institutions that, if they were lost, makes the abuse of power so much more available.”

Explaining his decision not to run for nomination at the last election, Mr Biden said in 2016: “I lost part of my soul when my boy died.

“You should never, ever, ever commit to run for president unless you know you can look the people in the eye and say: 'I guarantee you, you have all of my being, all of my energy, all of my family's energy to get this done.' I wish I were a better man but I just wasn't ready to do that."
