Donald Trump's last remaining Republican rival for the US election in November bashed the ex-president Sunday for his continued silence over the death of Russian opposition leader Alexei Navalny and his recent outburst over NATO.
"The fact that he won't acknowledge anything with Navalny -- either he sides with (Russian President Vladimir) Putin and thinks it's cool that Putin killed one of his political opponents, or he just doesn't think it's that big of a deal," Nikki Haley said on ABC's "This Week."
