A fourth woman accusing Donald Trump of sexual harassment is joining calls for Congress to investigate sexual misconduct claims against the president.

In an interview with Megyn Kelly on the Today show, Melinda McGillivray recounted her 2003 run-in with the now President. McGillivray is one of more than a dozen women who accused Trump of past sexual misconduct during his presidential campaign last year.

McGillivray told Kelly that Trump grabbed her right butt cheek during a 2003 event at Mar-a-Lago. She said she initially thought her friend's camera bag brushed against her, but quickly realized it was actually Trump's hand.

"If he’d accidentally nudged me he could have said excuse me, but he said nothing," she told Kelly, adding, "he knew what he did."

McGillivray, who said she's still shocked Trump was elected, is now joining calls from other accusers for Congress to investigate the accusations.

“He has to face the music, he can’t get away with this," McGillivray said. "...I want justice.”

President Trump has continued to deny accusations of misconduct. He tweeted Tuesday morning that he's never met accusers and called the renewed attention on sexual misconduct accusations a distraction.

"Despite thousands of hours wasted and many millions of dollars spent, the Democrats have been unable to show any collusion with Russia, so they are moving on to the false accusations and fabricated stories of women who I don't know and/or have never met. FAKE NEWS!," the president said in a tweet.

Three other women who accused president Trump of sexually harassing or assaulting them before he was elected spoke about their experiences during a press conference Monday.

"People are being held accountable, except for our president," said Jessica Leeds, who said Trump tried to force himself on her, including reaching under her skirt, during a plane ride more than 30 years ago. Yet "his staff made a big point of calling us all liars," she said.

The appearances on Monday and Tuesday come shortly after Nikki Haley, the U.S. ambassador to the United Nations, said that anyone who claims they were victims of sexual misconduct should be heard, even if Trump is the alleged perpetrator.

Sen. Bernie Sanders, I-Vt., also suggested Sunday that Trump should resign. “Here you have a president who has been accused by many women of assault, who says on a tape that he assaulted women,” Sanders said on Meet the Press. “He might want to think about doing the same.”

On Vice News, Sen. Cory Booker, D-N.J., said “The fact pattern on him is far more damning than the fact pattern on Al Franken."
