Hillary Clinton is still considering another run for the White House in 2020, according to reports.

CNN's Jeff Zeleny said Sunday on: 'Clinton is telling people that she’s not closing the doors to the idea of running in 2020.'

'I’m told by three people that as recently as this week, she was telling people that look, given all this news from the indictments, particularly the Roger Stone indictment, she talked to several people, saying "Look, I’m not closing the doors to this."'

However she has not set up an official campaign and has not said publicly she will run in 2020.

One of Hillary's friends also said they would be 'surprised' if she tried again, according to Zeleny.

Zeleny added: 'Most losing presidential candidates never totally close the doors to running for president.

'But I think we have to at least leave our mind open to the possibility that she is still talking about it.

'She wants to take on Trump. Could she win a Democratic primary to do it? I don't know the answer to that.'

On Saturday night, President Trump tweeted about both Hillary and Roger Stone.

He wrote: 'CBS reports that in the Roger Stone indictment, data was “released during the 2016 Election to damage Hillary Clinton.” Oh really! What about the Fake and Unverified “Dossier,” a total phony conjob, that was paid for by Crooked Hillary to damage me and the Trump Campaign?

'What about all of the one sided Fake Media coverage (collusion with Crooked H?) that I had to endure during my very successful presidential campaign.

'What about the now revealed bias by Facebook and many others. Roger Stone didn’t even work for me anywhere near the Election!'

He then wrote: 'WITCH HUNT'.

Stone, a Trump ally and a longtime Republican operative, did not rule out on Sunday cooperating with Special Counsel Robert Mueller in his investigation of Russian meddling in the 2016 U.S. presidential election.

Arrested at his waterfront home in Florida on Friday in a dawn raid by FBI agents, Stone told reporters he would not 'bear false witness against the president.'

Stone was charged with lying to Congress about the Trump campaign's efforts to use stolen emails to undercut Democratic rival Hillary.

Asked on ABC's "This Week" if he would cooperate with Mueller, he said: "You know, that's a question I would have to - I have to determine after my attorneys have some discussion."

"I'd also testify honestly about any other matter, including any communications with the president," he said. "It's true that we spoke on the phone, but those communications are political in nature, they're benign, and there is certainly no conspiracy with Russia."

Stone, 66, will be arraigned in federal court in Washington on Tuesday.

If Clinton does decide to throw her hat in the ring one more time, she would need to emerge from a large and formidable pool of Democrats who have either announced they are running or are on the verge of doing so.

If Clinton does decide to run, she will need to contend with a crowded Democratic field, which includes U.S. Senator Kamala Harris. Harris (above) launched her campaign for President at a rally in Oakland, California on Sunday

U.S. Senator Kamala Harris launched her 2020 White House campaign on Sunday with attacks on Trump’s policies at a rally in her hometown of Oakland, California, less than a mile from the courthouse where the Democrat began her career as a prosecutor.

The event’s location was the latest sign she plans to emphasize her track record as San Francisco’s district attorney and California’s attorney general.

Her 2020 slogan, 'Kamala Harris, for the people,' nods at the introduction she used in court and is a phrase she calls her 'compass.'

'My whole life, I’ve had only one client: The People,' Harris said at the rally, mentioning fighting for sexual assault survivors and prison diversion programs she created as a prosecutor.

The only former top city and state prosecutor in the race so far, the first-term California senator’s roots will differentiate her in a crowded field of Democrats seeking to run against Trump, the likely Republican nominee.

Senators Elizabeth Warren and Kirsten Gillibrand are in the race, and more U.S. senators are weighing bids.
