US election

"The heat has to be turned up so much that as a community, we've got to hold our vote," Diddy told the Rev. Al Sharpton on MSNBC Sunday. "Don't pacify yourself; really revolutionize the game. Make them come for our vote. It's a whole different strategy, but I think we need to hold our vote because I don't believe any of them."

The entertainment icon explained that while he thinks that Obama has done "an excellent job" as president, he also feels that the first black presidency didn't fully deliver on its promise.

He told the congregation he "fully understands that the African American community has suffered discrimination".

Polls say Mr Trump, who is lagging behind Mrs Clinton, has low support among black and Hispanic voters.

He was accompanied by Ben Carson, the former Republican presidential hopeful who grew up in the city.

Mr Trump has put his vow to toughen the country's immigration policies at the centre of his campaign.

He has promised to carry out mass deportations and build a wall on the US-Mexico border — proposals that critics have assailed as inhumane and too costly and unrealistic to achieve.

He'd lost his swagger. His mojo was flat.

That was this time last week.

Donald Trump, the Teflon terminator who breezed through the primaries dropping flaming bombs of rhetoric that would have choked any other campaign, was suddenly looking vulnerable.

He loves to cite poll numbers, when they're good, but when they're almost universally bad what is there to talk about?

Hacking tools allegedly developed by the US National Security Agency (NSA) were dumped online by a group calling itself Shadow Brokers.

It follows a string of recent leaks of data from the Democratic National Committee (DNC).

There are also now suspicions that the Clinton Foundation, a charitable body, mayhave been targeted.

The proposal, outlined in a speech in Ohio, includes temporarily suspending visas from countries with terrorist ties as well as introducing an ideological test for those entering the US.

Though Mr Trump has yet to outline which countries would be included on the list, he told supporters at the rally he would "ask the State Department and Department of Homeland security to identify regions where adequate screenings cannot take place".

The paper said ledgers earmarked $12.7m (£9.8m) in undisclosed cash payments from a pro-Russia political party in Ukraine to Mr Trump's campaign head Paul Manafort between 2007 and 2012.

His lawyer said Mr Manafort had not received any such payments.

The Democratic presidential candidate paid an effective federal tax rate of 34.2% last year.

Her running mate Tim Kaine, along with his wife Anne Holton, paid a rate of 20.3%, his returns show.

Mr Trump, a hotel developer with a fortune estimated to be in the billions, has refused to release his.

Presidential candidates typically release their tax returns to the media to show their effective tax rate, charitable donations and other financial details.

Speaking at a rally in a high school gym in Pennsylvania, Mr Trump attacked Bernie Sanders for capitulating to Mrs Clinton in the Democratic race.

"He made a deal with the devil," the tycoon said. "She's the devil."

Democrats and Republicans alike have condemned Mr Trump for his remarks about a US Muslim soldier's parents.

Mr Obama praised Mrs Clinton at the Democratic convention in Philadelphia, as the most qualified person ever to run for the White House.

He said voters faced a choice between hope and fear, attacking "home-grown demagogue" Republican Donald Trump.

Mr Trump responded by rejecting the president's optimistic portrayal.

"Our country does not feel 'great already' to the millions of wonderful people living in poverty, violence and despair," he said on Twitter.
