Former governor of Massachusetts and 2020 Republican presidential candidate Bill Weld said President Trump would prefer a “Aryan nation” during a Q&A at the Edward M. Kennedy Institute.

Weld is the sole current Republican challenger to Trump in 2020 and has said he will run a “ferocious” campaign against the president.

“I celebrate that America has always been a melting pot. It seems he [Trump] would prefer an Aryan nation. I know that sounds strong and tough but he’s very interested in bloodlines and it has resonance,” Weld said during while reading a prepared description of his platform at the institute’s “Getting to the Point” program on May 21.
