Sanders, delegates to meet privately amid lingering angst

The emails angered many Sanders supporters who were already dismayed by Clinton's choice on Friday of low-key US Senator Tim Kaine of Virginia as her vice presidential running mate.

Wasserman Schultz was also considered a close friend of Arizona Rep. Gabrielle Giffords, who was critically wounded during a shooting rampage in Tucson.

Inside the Wells Fargo Center, some Democrats are preparing to nominate Hillary Clinton as the party's candidate for president.

The Vermont senator will emphasise that the Democratic Party's "most progressive" platform in its history includes agreements he reached with Clinton to drastically increase access to health care and make tuition at public universities free for students from families with incomes below $125,000 per year, EFE news reported citing the statement.

The Democratic National Convention that is to formally nominate Hillary Clinton as the party's presidential candidate is getting off to a torrid start amid a heat wave on Monday with rancor and a mini mutiny in the ranks.

Sanders will address the convention Monday night, and Obama will speak on Wednesday night.

In one email out of the 20,000 leaked, the committee's Chief Financial Officer Brad Marshall appears to float an idea to question Sanders' Jewish faith. Sanders had called earlier Sunday for her departure. "We're going to talk about the future", Gallego said. He believes that the DNC was "at opposition to our campaign" all along, he said Sunday morning.

Bernie Sanders had pressed for Wasserman Schultz to quit on the eve of the convention. "And no one works harder for her constituents in Congress than Debbie Wasserman Schultz". Schultz was the co-chair of her 2008 bid for president.

Democratic National Committee communications director Luis Miranda tweeted that Donna Brazile will service as interim chair "through the election".

Higgins is part of a pro-Sanders group that walked 140 miles over nine days from Washington, arriving Saturday evening.

"She was never going to be the permanent chairman of the convention", Frank said in an interview on Sunday.

Blowback to the emails came from all corners of the political world Sunday - including Clinton supporters and Donald Trump.

It is a spectacular fall from grace for the tough-talking Florida representative, who became the first woman elected to chair the Democratic National Committee. "I think, as I said, it's what we talked about six months ago" Sanders said. "Just too much extremism", Madigan said.

Even while Sanders sought to redirect the outrage over the leaked emails and urged his supporters to focus on Trump, he acknowledged that Kaine is not the vice presidential pick he had hoped for.
