Eric Trump on Father's Threat to Sue Accusers: 'My Father's a Fighter'

— -- Eric Trump commented on his father's vow to sue every woman who has accused him of sexual misconduct, saying, "He's a fighter ... and he believes in calling out right and wrong."

"My father's a guy who will fight. He'll fight for this country. And he's always fought for himself and, quite frankly, throughout this whole process he's needed to fight for himself," the son of the Republican presidential nominee told ABC’s George Stephanopoulos in an exclusive interview on “This Week.”

"Quite frankly, he's a great fighter, and he believes in calling out right and wrong," Trump said.

Donald Trump spoke Saturday in Gettysburg, Pennsylvania, on his plan for his first 100 days in office if he is elected, but began his address by criticizing the “dishonest” media, the “rigged” political system, and pledging that after the election he will sue every woman who has accused him of sexual misconduct.

"Every woman lied when they came forward to hurt my campaign. Total fabrication," the Republican nominee said in his speech at a hotel near the historic Gettysburg battlefield. "The [alleged] events never happened. Never. All of these liars will be sued after the election is over."

Eric Trump also addressed a claim by People magazine reporter Natasha Stoynoff, who wrote about an alleged instance when Donald Trump pushed her against a wall and forced "his tongue down my throat," in the mid-2000s.

The Republican nominee's son dismissed Stoynoff's account as somehow tied to the campaign of Democratic candidate Hillary Clinton, telling Stephanopoulos, "I just don't believe it."

He said he was warned months ago to "get ready for October ... What the Clinton machine will throw at you, you know, the dirty tricks, the things that will come out, the things that they'll orchestrate."

Asked if his father is prepared to accept the election results no matter the outcome, Trump said: "My father will accept it 100 percent, if it's fair."

He also dismissed new ABC News tracking poll numbers showing Clinton leading by double digits. "The polls are all over the place," Trump said, adding that the level of enthusiasm for his father's candidacy is "off the charts."

"I think we're going to do very well and I really believe we're going to win this," Trump said.
