MSNBC commentator Donny Deutsch warned of the consequences to the Trump presidency if adult-film star Stormy Daniels says she was threatened with physical harm.

"Is it fair to say, legal aside, if Stormy Daniels comes out and says that she was ... physically threatened harm by either the president himself or somebody very close, that, and it seems to be credible, that in and of itself would bring down this presidency with what is going on in the world right now," Deutsch said on MSNBC's "Morning Joe."

He urged others on to think about what that could mean.

His comments come after Daniels's attorney on Friday said his client had been threatened with physical harm in connection to her alleged affair with Trump.

Asked on "Morning Joe" whether Daniels, whose real name is Stephanie Clifford, had ever been threatened with physical harm, Michael Avenatti, replied, "Yes."

It wasn't clear who allegedly threatened Daniels or what the exact nature of the threats was.

Deutsch said the comments were "nothing short of stunning."

Daniels is suing to void a nondisclosure agreement that she says prevents her from speaking out about her alleged affair with Trump more than a decade ago.

She was paid $130,000 by Trump's personal attorney, Michael Cohen, weeks before the 2016 presidential election. She says the payment was intended to buy her silence about the alleged affair.

Cohen has acknowledged making the payment to Daniels but insisted the funds came from a personal account and were not tied to the Trump campaign.

The White House has denied Trump ever had an affair with Daniels.
