Stormy Daniels, a former porn star, sued President Donald Trump on Tuesday over a nondisclosure agreement meant to conceal an affair.

The lawsuit contains a copy of the NDA with a blank line in the spot where it appears Trump was supposed to sign.

Daniels has argued that the NDA is null and void because Trump never signed it.

The former adult-film star Stormy Daniels sued President Donald Trump on Tuesday, arguing that a "hush agreement" to conceal an affair is invalid because he never signed it.

The 28-page lawsuit, which contains a copy of the nondisclosure agreement, gives a striking glimpse into Daniels' side of the story.

It corroborates several statements Daniels, whose real name is Stephanie Clifford, made in a 2011 interview with In Touch magazine, including that she and Trump met and had a sexual encounter in Lake Tahoe, Nevada, in 2006.

Twelve days before the 2016 presidential election, Michael Cohen, Trump's personal lawyer, paid Daniels $130,000.

It's unclear how Daniels' lawsuit will fare in court, but the filing released on Tuesday provides details she has previously been coy about in interviews.

Here are some of the highlights from the lawsuit:

The suit says Daniels had an "intimate relationship" with Trump from the summer of 2006 into 2007.

Daniels first decided she wanted to speak publicly about her affair with Trump after The Washington Post published the infamous "Access Hollywood" recording from 2005 that featured Trump boasting about grabbing women's genitals and attempting to seduce a married woman.

But when Daniels began shopping the story to media outlets, Trump and Cohen "aggressively sought to silence" her.

Daniels and her attorneys argue that Trump's efforts to keep her quiet helped "to ensure he won the Presidential Election." The nondisclosure agreement used the aliases David Dennison and DD to refer to Trump, and Peggy Peterson and PP to refer to Daniels.

The suit says "it was widely understood at all times" that all parties had to sign the agreement, otherwise it would be null and void.

The suit further argues that Trump "purposely did not sign the agreement so he could later, if need be, publicly disavow any knowledge of the Hush Agreement" and Daniels.

The suit accuses Cohen of intimidating and coercing Daniels into signing a false statement in January denying that she had an affair with Trump and received hush money. Daniels had previously expressed skepticism about the statement, saying in an interview with the late-night host Jimmy Kimmel that the signature on it "doesn't look like my signature, does it?"

The suit contains a copy of the nondisclosure agreement that shows a blank line where "DD" was supposed to sign.

The NDA also includes a reference to "certain still images and/or text messages which were authored by or relate to DD," raising the possibility that Daniels may release photos or texts related to Trump if the court voids the NDA.
