Seeking to re-set the presidential race, Donald Trump unveiled his "closing arguments" speech Saturday that included an agenda for his first 100 days in office and attacks on Hillary Clinton, the media and critics in general.

"They are trying to poison the mind of the American voter," Trump said of the media during remarks in Gettysburg, Pa.

He also vowed to file lawsuits against the women who have accused him in recent weeks of inappropriate sexual behavior, saying: "All of these liars will be sued after the election is over."

Trump also reiterated his pledges to build an anti-migration wall along the U.S.-Mexico border and to ban the entry of Muslims to the United States from countries with histories of terrorism and poor vetting procedures.

Trump, who has accused opponents of rigging the election against him, again raised the specter of voter fraud. He said — without evidence — that "1.8 million dead people are registered to vote, and some of them are voting."

Trump's issue agenda included pushes for tax cuts, reduced federal regulations and revamped trade deals with other countries. Describing his first 100-day plan as "a contract between Donald J Trump and the American voter," the candidate also proposed term limits for members of Congress and lobbying restrictions on former government employees.

He also accused the FBI and Justice Department of covering up crimes by Democrat Hillary Clinton involving her private use of e-mail while secretary of State.

The closing arguments speech — a late addition to his schedule — comes amid polls showing him trailing Clinton both nationally and in key battleground states. On social media, Trump cited other polls showing him inching ahead of Clinton. He tweeted: "The media refuses to talk about the three new national polls that have me in first place. Biggest crowds ever - watch what happens!"

In the wake of three debates against Clinton, Trump has also contended with allegations from a variety of women claiming he made inappropriate sexual advances toward them. Trump has denied the accusations, and called them part of an effort to "rig" the election against him.

After his speech in Gettysburg, Trump hosts rallies Saturday in two politically important states, Virginia and Ohio. On Sunday, he travels to the must-win state of Florida, part of what he and aides described as a stepped-up schedule for the last two-and-a-half weeks of the campaign.

"Right up until the actual vote of November 8th," Trump said Friday in North Carolina. "And then I don't know what kind of shape I'm in but I'll be happy and at least I will have known, win, lose or draw, and I'm almost sure if the people come out we're gonna win."

Miller said Trump's Gettysburg speech is designed to "set the tone" for the final days of the campaign, and that the candidate will argue he is the "change agent" the country needs.

“The Donald Trump campaign is a movement unlike anything we’ve seen in our country’s history," Miller said.
