Donald Trump says he does not need the help of the Republican party to win the US presidential election.

On Twitter, Mr Trump called House Speaker and party colleague Paul Ryan a "very weak and ineffective" leader who was offering "zero support" for his campaign.

He later tweeted to say he was pleased "the shackles have been taken off me and I can now fight for America the way I want to", adding: "Disloyal Rs are far more difficult than Crooked Hillary. They come at you from all sides. They don't know how to win - I will teach them!".

Mr Ryan responded to the jibes by urging Mr Trump to spend more time trying to defeat Democrats than fighting fellow Republicans.

Meanwhile during a speech in Florida, he urged supporters to go out and vote for him on November the 28th - which is the wrong date.

US voters go to the polls on November 8th. He used the correct date later in his address.

At the same rally, Mr Trump praised Wikileaks for releasing hacked rival Hillary Clinton's campaign documents, claiming they showed his opponent "is the vessel (of) a corrupt global establishment that's raiding our country and surrendering the sovereignty of our nation".

Mrs Clinton's campaign chairman John Podesta said the FBI was investigating the "criminal" hack of his e-mails.

He also claimed Russia was responsible for the hack and could be colluding with the Trump campaign.

Meanwhile US President Barack Obama has branded Mr Trump "repugnant" following the leak of a video which showed him boasting about groping women.

White House spokesman Josh Earnest said there was wide agreement that Mr Trump's comments on the recording "constituted sexual assault".

He said the president found the tape "as repugnant as most Americans did".

In the clip, Mr Trump brags about women letting him kiss and grope them because he is famous, saying "when you're a star they let you do it".

He continues: "Grab them by the p****. You can do anything."

Following the release of the video, Mr Trump initially said he was sorry "if anyone was offended" by the "locker room banter".

A more forthright apology saying he regretted the incident was issued after a backlash which saw party colleagues desert him.

Meanwhile campaigners have called on the makers of the US version of 'The Apprentice' to release more footage rumoured to show Mr Trump making offensive remarks.

Civil rights lawyer Gloria Allred - a Hillary Clinton supporter - was joined at MGM's offices by women's groups, where she said it was in the "public interest" that the tapes be disclosed "immediately, unless there is a legal prohibition to doing so".
