Citadel founder Ken Griffin signaled his attention in US presidential debates remained on Nikki Haley, putting his hopes on a “great night” for her.

“If she does, I think that could be a galvanizing moment for her campaign,” Griffin said at the Bloomberg New Economy Forum on Thursday in Singapore with the third Republican debate underway in Miami.

When asked if he believed she could beat Donald Trump in the primaries, Griffin said “it’s going to come down to how does the American public incorporate the legal morass that former President Trump’s enmeshed in.”

Griffin said he believes that Trump is being “100%” politically persecuted and a number of the charges against him are “really flimsy.”

Griffin has called Haley, the former US ambassador to the United Nations, a “rock star” on the campaign trail and said she has the experience to be in the Oval Office.

The New Economy Forum is being organized by Bloomberg Media Group, a division of Bloomberg LP, the parent company of Bloomberg News.
