"I am already receiving messages from leaders," Clinton told an Ohio audience at a Democratic presidential town hall on Sunday night.
"I'm having foreign leaders ask if they can endorse me to stop Donald Trump."
Clinton, the Democratic front-runner, said she didn't want to "spill the beans right now, but suffice it to say, there are many arguments that we can use against him."
"But one argument that I am uniquely qualified to bring, because of my service as secretary of State, is what [Trump's] presidency would mean to our country and our standing in the world."
CNN moderator Jake Tapper asked Clinton who the foreign leaders were who had been reaching and asking if they could endorse her to stop Trump.
"Some have done it publicly, actually," Clinton replied, singling out Italian Prime Minister Matteo Renzi.
Tapper pressed her about who the private messages had come from.
"No. ... We're holding that in reserve," Clinton responded with a laugh.
"I believe that I will have an opportunity to really focus in on how dangerous a Donald Trump presidency would be, for our standing, for our safety, for the peace of the world."
