"As a senator, I think she passed, she has her name on three laws in eight years," Bush told Fox News' Sean Hannity in New Hampshire. "And as secretary of state, in all honesty, the things she's known for, the reset [with Russia], the pulling back of our commitments, Libya -- put aside Benghazi, Libya in general -- it turns out it was a complete failure."
"I honestly don't know what her successes are," he added.
Bush also spoke about his family, saying he's "blessed to be Jeb Bush" but noting he doesn't expect to win anything based on heredity.
"I know if I'm going to be successful, I have to make my own way as a candidate," he said.
