US Republican presidential candidate Donald Trump has vowed to launch post-election lawsuits against every woman who has accused him of sexual assault or other inappropriate behaviour.

During a speech in Gettysburg, Trump accused Hillary Clinton’s campaign and the Democratic Party with orchestrating the allegations.

“Every one of these liars will be sued once the election is over,” Mr Trump said.

“I look so forward to doing that.

“Every woman lied when they came forward to hurt my campaign.”

Ten women have publicly accused Mr Trump of unwanted advances or sexual assault in the weeks since a 2005 recording emerged in which the former reality TV star made sexually aggressive comments about women.

Mr Trump has denied all allegations while insisting some of the women were not attractive enough for him to want to pursue.

Trump has lashed out at US media companies, saying they are biased against him and he’ll break up their power structures if he’s elected president.

Trump has promised to foil a proposed deal for AT&T Inc to buy Time Warner Inc if he wins the November 8 election, arguing it’s an example of a “power structure” rigged against him and voters.

Trump on Saturday listed his policy plans for the first 100 days of his presidency, but also defiantly raised personal grievances, describing how he would address them from the White House.

“They’re (media companies) trying desperately to suppress my vote and the voice of the American people,” he told supporters in his speech.

“As an example of the power structure I’m fighting, AT&T is buying Time Warner and thus CNN, a deal we will not approve in my administration because it’s too much concentration of power in the hands of too few.”

He also said he would look at “breaking” up Comcast’s acquisition of NBC Universal in 2013.

“Deals like this destroy democracy,” he said.

Although Trump, a wealthy New York businessman, described these plans at least in part as a response to his belief such organisations had treated him unfairly, he argued that less wealthy voters had even greater cause to worry.

“When a simple phone call placed with the biggest newspapers or television networks gets them wall to wall coverage with virtually no fact-checking whatsoever, here is why this is relevant to you,” he said.

“If they can fight somebody like me who has unlimited resources to fight back, just look at what they could do to you, your jobs, your security, your education, your health care.”

Trump arguably had simultaneously the best and worst moments of his tumultuous campaign during a gala speech on Friday.

Mr Trump delivered the speech at the light-hearted Al Smith Charity Dinner in Manhattan where he was joined by bitter rival Hillary Clinton.

The pair traded self-deprecating gags and at times vicious jibes toward one another, just 24 hours after their bitter third Presidential debate.

But as quickly as Mr Trump whipped the audience into fits of laughter, the room deteriorated into booing and heckling when the controversial billionaire crossed a line during the normally jovial affair.

The crowd’s mood drastically changed when Mr Trump referred to Ms Clinton as “corrupt” for being “kicked off the Watergate commission”.

The moment the crowd turned:

And just in case you missed the guy in the room who looked the most shocked …

La Trobe University American politics lecturer Kumuda Simpson told The New Daily the pair’s speeches were abnormally “nasty”.

“After such a toxic campaign I was surprised they had to share the stage and make fun of each other,” Ms Simpson said.

“The jokes were aimed at each other a lot more than in the past.”

Here are some more of the candidates’ best lines from the dinner, followed by both Mr Trump and Ms Clinton’s speeches in full.

Mr Trump likes Rosie O’Donnell more, thanks to Ms Clinton

“Last night [at the third debate I called Hillary ‘a nasty woman’. But this stuff is all relative. After listening to Hillary rattle on and on and on, I don’t think so badly of Rosie O’Donnell anymore. In fact, I’m actually starting to like Rosie a lot.”

Media bias

“Hillary got the chance to meet my campaign manager and I got the chance to meet the people working so hard to get her elected. There they are — the heads of NBC, CNN, CBS, ABC, there’s the New York Times right there and the Washington Post.”

Ms Clinton’s paid speeches

“I’ve known Hillary for a long time, this is the first time ever Hillary is sitting down with major corporate leaders and not getting paid for it.”

Ms Clinton bakes former NYC Mayor and Trump ally, Rudy Giuliani. And he doesn’t like it one bit

“Many don’t know this, but Rudy actually got his start as a prosecutor going after wealthy New Yorkers who avoided paying taxes,” she said. “But as the saying goes, if you can’t beat them, go on Fox News and call him a genius.”

LOL Rudy Giuliani is so not impressed with HRC's joke. https://t.co/GgfNMKAzwF

Ms Clinton pokes fun at herself

“I took a break from my rigorous nap schedule to be here … Usually I charge a lot for speeches like this.”

Even Melania Trump wasn’t safe

“Michelle Obama gives a speech, and everyone loves it … My wife Melania gives the exact same speech and people get on her case, and I don’t get it!”

Ms Clinton hits Trump for sexism

“People look at the Statue of Liberty and they see a proud symbol of our history as a nation of immigrants. A beacon of hope for people around the world. Donald looks at the Statue of Liberty and sees a four. Maybe a five if she loses the torch and tablet and changes her hair.”
