WASHINGTON (Sputnik) — Pyongyang confirmed earlier in the day that it had tested a nuclear warhead at its northeastern nuclear test site. The experiment was its fifth nuclear test and the largest ever performed by North Korea.
"North Korea's fifth nuclear test, the fourth since Hillary Clinton became Secretary of State, is yet one more example of Hillary Clinton's catastrophic failures as Secretary of State," Miller stated.
He noted that Clinton promised to work on ending the North Korean nuclear program while serving as the United States' top diplomat, but the program has "only grown in strength and sophistication."
Clinton served as US Secretary of State between 2009 and 2013.
