Presidential candidate Nikki Haley wouldn't say if she'd support Donald Trump as the GOP nominee, saying she's running against him. Haley criticized Trump for his silence on the death of Russian opposition leader Alexei Navalny, calling it concerning he sides with Putin. She accused Trump of empowering Putin by saying he'd let Russia invade NATO allies not meeting spending goals. Haley called Putin "not a friend" and said the US must stand with Navalny's supporters and Ukraine against Russian aggression.
