Stormy Daniels's attorney said a picture he tweeted of a compact disc he says has proof of President Trump's alleged affair with the porn star was a "warning shot" to the president. 

"I want to be really clear about this: It is a warning shot. And it's a warning shot to Michael Cohen and anyone else associated with President TrumpDonald John TrumpHouse Republican threatens to push for Rosenstein impeachment unless he testifies Judge suggests Trump’s tweet about Stormy Daniels was ‘hyperbole’ not defamation Rosenstein faces Trump showdown MORE that they better be very, very careful after Sunday night relating to what they say about my client and what spin or lies they attempt to tell the American people," attorney Michael Avenatti told CNN's Wolf Blitzer on Friday night.

Avenatti on Thursday night tweeted a picture of a CD inside a safe, asking, "If 'a picture is worth a thousand words,' how many words is this worth?????"

The attorney has indicated Daniels, whose real name is Stephanie Clifford, has hard evidence of her story about an alleged affair with Trump. 

Avenatti on Friday said the tweet was not a "tease" and that he has evidence of the affair, although he did not indicate when it would be released. He refused to provide any hints or examples.

"People better be honest, because they haven't been honest in the past, relating to this relationship, relating to the bullying tactics, relating to the threats and intimidation," Avenatti told Blitzer. "It is time to come clean."

Avenatti is currently representing Daniels in her lawsuit against Trump to scrap a nondisclosure agreement she says is invalid because Trump never signed it.
