Steering his campaign toward controversy yet again, Donald Trump vowed Saturday to sue every woman who has accused him of sexual assault or other inappropriate behavior. He called them "liars" whose allegations he blamed Democrats for orchestrating.

Trump's blunt threat of legal action -- hours before an 11th accuser spoke out with claims of sexual misconduct -- eclipsed his planned focus on serious-minded policy during a speech in Gettysburg. Though his campaign had billed the speech as a chance for Trump to lay out a to-do list for his first 100 days as president, he seemed unable to restrain himself from re-litigating grievances with Hillary Clinton, the media and especially the women who have come forward in recent days.

"All of these liars will be sued once the election is over," Trump said. He added later: "I look so forward to doing that."

Eleven women have publicly accused Trump of unwanted advances or sexual assault in the weeks since a 2005 recording emerged in which the former reality TV star boasted of kissing women and groping their genitals without their consent. The latest came on Saturday, when an adult film actress said the billionaire kissed her and two other women on the lips "without asking for permission" when they met him after a golf tournament in 2006.

Jessica Drake also alleged that when she declined to spend time with Trump later that night he said she could use his private jet, and she said either Trump on someone on his behalf offered her $10,000. She said she refused.

Trump has denied all the allegations, while insisting some of the women weren't attractive enough for him to want to pursue. His campaign called the latest accusations "totally false and ridiculous."

"Every woman lied when they came forward to hurt my campaign," Trump said Saturday in Pennslyvania. Without offering evidence, he surmised that Clinton or the Democratic National Committee had put the women up to it.

Speaking to reporters aboard her campaign plane, Clinton dismissed as "inaccurate" the suggestion that Democrats or her campaign were encouraging women to level accusations against Trump. She said that, after three debates, she wasn't thinking about responding to what Trump says anymore and would "let the American people decide what he offers and what we offer."

Clinton said she would be focusing the remaining days before the election helping down-ballot Democrats. To that end, she assailed the state's Republican senator, Pat Toomey, saying in Pittsburgh that he has refused to "stand up" to Trump as she touted his Democratic challenger, Katie McGinty.

Noting Trump's comments about Mexican immigrants and his attacks on a Muslim-American military family, she said of Toomey: "If he doesn't have the courage to stand up to Donald Trump after all of this, then can you be sure that he will stand up for you when it counts?"

Trump's broadside against the women came at the start of an otherwise substantive speech that sought to weave the many policy ideas he has put forward into a single, cohesive agenda that he said he would pursue aggressively during his first three months in office.

The Republican nominee vowed to lift restrictions on domestic energy production, label China as a currency manipulator and renegotiate the North American Free Trade Agreement, familiar themes to supporters who have flocked to his rallies this year.

"This is my pledge to you, and if we follow these steps, we will once again have a government of, by and for the people," Trump said, invoking a phrase from President Abraham Lincoln's Gettysburg Address.

Though mostly a recap of policies he's proposed before, Trump's speech included a few new elements, such as a freeze on hiring new federal workers and a two-year mandatory minimum sentence for immigrants who re-enter the U.S. illegally after being deported a first time. In a pledge sure to raise eyebrows on Wall Street, he said he'd block a potential merger between AT&T and media conglomerate Time Warner.

Translating his proposals into digestible bullet points, he offered to-the-point titles for the legislative vehicles he'd need Congress to approve to accomplish his goals, such as the "End Illegal Immigration Act" and the "Repeal and Replace Obamacare Act."

Throughout the GOP primary, Trump was criticized for shying away from detailed policy proposals. But his speech, which aides said would form the core of his closing argument to voters, underscored how the billionaire has gradually compiled a broad — if sometimes vague — policy portfolio that straddles conservative, isolationist and populist orthodoxies.

Yet any headway that Trump may have made was likely to be diluted by his legal threats against his accusers, just the latest example of Trump stepping on his intended message at inopportune moments. Days earlier, during the final debate, his otherwise well-received performance was marred by an alarming statement near the end that he might not accept the outcome of the election if he loses.

Trump didn't say what kind of lawsuits he planned to file against the women, but any libel litigation could be complicated by the fact that Trump, in the 2005 recording, bragged about the same kind of conduct the women now accuse him of perpetrating. Trump recently vowed to sue The New York Times for libel, but has not yet followed through on the threat.

With the debates now over, Trump and Clinton have few apparent opportunities to alter the course the race substantially — a reality that benefits Clinton more than Trump. The Republican is trailing his opponent in most of the battleground states while Clinton eyes potential upset victories in traditionally safe GOP territory, with Arizona at the top of the list.

An increasingly confident Clinton on Saturday made what's become her closing pitch in Pittsburgh, stressing unity and asking her backers to carry her message to any Trump supporters they meet.

"I understand that they need a president who cares about them, will listen to them and I want to be their president," she said.

As Election Day nears, Clinton is also focusing on getting Democrats elected to Congress. She attacked the state's Republican senator, Pat Toomey, saying he has refused to "stand up" to Trump as she touted his Democratic challenger, Katie McGinty.

Her campaign headquarters in New York was back up and running after a scare over an envelope that arrived containing a white powdery substance. Initial tests showed the substance wasn't harmful.

Meanwhile, Clinton was getting a campaign boost from singer and pop icon Katy Perry, who was pushing early voting in Las Vegas. The singer surprised students at the University of Nevada Las Vegas when she knocked on the doors of their dorm rooms wearing a T-shirt that read "Nasty Woman," a phrase Trump uttered at Wednesday's debate in reference to Clinton. She headlined a short outdoor rally on campus but didn't perform any of her songs.

Miley Cyrus also stumped for Clinton by knocking on doors at a college. She met with young voters at George Mason University in Virginia.

More than 4.4 million votes have already been cast. Data compiled by The Associated Press found that Clinton appeared to be displaying strength in crucial North Carolina and Florida, while Trump appeared to be holding ground in Ohio, Iowa and Georgia.
