The Donald also surprised his wife, saying she will be appearing more on the campaign trail in the days leading up to the election.
Melania Trump has condemned the women who have come forward with claims of sexual misconduct at the hands of her husband.
“To accuse somebody without evidence, it's very hurtful and it's very damaging and unfair,” she told George Stephanopoulos on Thursday’s Good Morning America.
Trump’s third wife backed her husband’s vow to sue his accusers.
“They were lies, and as I said before, all the accusations should be handled in a court of law,” Donald Trump told the ABC anchor.
Stephanopoulos then turned to Melania, asking her: “So you believe the lawsuit should go forward?”
“Yes, I believe that,” she replied.
The former model was also asked whether she'll be helping her husband in the final days before the election.
“We will see,” Melania Trump responded. “My priority is my son Barron and I support [my husband] 100 percent and I’m there for him every time he needs me.”
Trump then interjected: “She is actually going to make two or three speeches. She's amazing when she speaks. She is an amazing public speaker. So she's agreed to do two or three speeches, and I think it's going to be big speeches, important speeches. I think it's going to be great."
A surprised Melania reacted, saying: “Oh!”
Melania's appearance on the campaign trail has diminished since her controversial RNC speech in July where she plagiarized parts from Michelle Obama's 2008 DNC speech.
