President Donald Trump targeted Democrats and the women who have accused him of sexual misconduct in a tweet Tuesday morning, calling their claims “false” and “fabricated.”

“Despite thousands of hours wasted and many millions of dollars spent, the Democrats have been unable to show any collusion with Russia — so now they are moving on to the false accusations and fabricated stories of women who I don’t know and/or have never met,” the president tweeted. “FAKE NEWS!”

While Trump claimed he did not “know and/or have never met” these accusers, several of the women had participated in events in which he was the host. Of the 19 women who have come forward with accusations against the president, one of them, Summer Zervose, was a contestant on the fifth season of NBC’s The Apprentice, and several of them were contestants in Miss USA pageants.

Additionally, one of them is Natasha Stoynoff, a former People magazine staff writer who interviewed Trump and Melania Trump in Mar-a-Lago in 2005, when, she said, Trump forced her against a wall and kissed her.

Their claims, many of which have a number of corroborators, were recently detailed again in The Atlantic and The Washington Post.

Trump’s tweet came after the White House told Megyn Kelly Today that the claims were “false” and “totally disputed in most cases by eyewitness accounts” — seemingly confirming, at least, that Trump at met at least some of his accusers.

The White House did not immediately respond to a request for comment from TIME Tuesday morning.

On Monday, three women who have accused Trump of sexual misconduct in the past spoke at a press conference and appeared on Megyn Kelly Today amid a national reckoning as more men in a variety of industries have been fired or forced to resign over accusations of sexual harassment or sexual assault. The women repeated their accusations on Kelly’s program Monday morning in light of newfound attention to the subject — and the momentum of the #MeToo movement.

The stories told by Samantha Holvey, Rachel Crooks, and Jessica Leeds included allegations that Trump came backstage unexpectedly and inspected contestants during the Miss USA pageant in 2006, and that he had forcibly kissed Crooks on the mouth at Trump Tower in 2005.

“In an objective setting, without question, a person with this record would have entered the graveyard of political aspirations never to return,” said Crooks said Monday. “Yet, here we are with that man as President.”

In recent weeks, a wave of allegations has resulted in men in a variety of industries resigning or being fired. The list includes former Minnesota Sen. Al Franken, who stepped down last week amid sexual misconduct allegations, as well as Michigan Rep. John Conyers.

Democratic lawmakers on Monday called on Trump to resign amid the allegations, as well as recommended a Congressional investigation into the claims. One of those lawmakers included New York Sen. Kirsten Gillibrand, whom Trump also targeted on Twitter on Tuesday.

“Lightweight Senator Kirsten Gillibrand, a total flunky for Chuck Schumer and someone who would come to my office ‘begging’ for campaign contributions not so long ago (and would do anything for them), is now in the ring fighting against Trump,” he tweeted. “Very disloyal to Bill & Crooked-USED!”

Gillibrand’s office did not immediately respond to a request for comment from TIME.
