Former US Vice-President Kamala Harris has said she may make another bid for the presidency, telling the BBC she could "possibly" be president one day.

In her first UK interview, Harris said she was confident there will be a woman in the White House in the future and made her strongest suggestion yet that she may run again in 2028 after losing to Donald Trump last year.

Speaking to Sunday with Laura Kuenssberg, Harris branded Trump a "tyrant" and said her warnings about him during the campaign had been proved right.

As the Democratic Party continues to reflect on Trump's decisive victory a year ago, much of the criticism has been aimed at former President Joe Biden for not stepping down sooner.

Questions have also been raised about whether Harris could have run a stronger campaign, particularly on economic issues.

In the BBC interview, Harris entertained the possibility of another run for the White House, saying her grandnieces would, "in their lifetime, for sure," see a female president. When asked if that person could be her, she replied, "possibly," confirming she is considering another run.

Harris added that she has not made a final decision but emphasized she still sees a future for herself in politics.

"I am not done," the former vice-president said. "I have lived my entire career as a life of service and it's in my bones."

Responding to polls placing her as an outsider for the Democratic nomination—even behind Hollywood actor Dwayne "The Rock" Johnson—Harris dismissed their relevance.

"If I listened to polls I would have not run for my first office, or my second office – and I certainly wouldn't be sitting here," she said.

She also argued that her predictions about Donald Trump running an authoritarian government had come true.

"He said he would weaponise the Department of Justice - and he has done exactly that," Harris said, pointing to the suspension of late-night comedian Jimmy Kimmel by ABC after a joke about Republican reactions to the death of right-wing influencer Charlie Kirk.

"You look at what has happened in terms of how he has weaponised, for example, federal agencies going around after political satirists… His skin is so thin he couldn't endure criticism from a joke, and attempted to shut down an entire media organisation in the process."

Harris also criticised US business leaders for yielding to Trump's influence.

"There are many… that have capitulated since day one, who are bending the knee at the foot of a tyrant, I believe for many reasons, including they want to be next to power, because they want to perhaps have a merger approved or avoid an investigation," she said.

The White House dismissed her comments, with spokeswoman Abigail Jackson saying, "When Kamala Harris lost the election in a landslide, she should've taken the hint - the American people don't care about her absurd lies. Or maybe she did take the hint and that's why she's continuing to air her grievances to foreign publications."

Harris has recently published her campaign memoir, 107 Days, detailing her turbulent journey to the 2024 election after Biden withdrew from the race amid speculation about his mental fitness.
