WASHINGTON — A special intelligence review of two emails that Hillary Rodham Clinton received as secretary of state on her personal account — including one about North Korea’s nuclear weapons program — has endorsed a finding by the inspector general for the intelligence agencies that the emails contained highly classified information when Mrs. Clinton received them, senior intelligence officials said.

Mrs. Clinton’s presidential campaign and the State Department disputed the inspector general’s finding last month and questioned whether the emails had been overclassified by an arbitrary process. But the special review — by the Central Intelligence Agency and the National Geospatial-Intelligence Agency — concluded that the emails were “Top Secret,” the highest classification of government intelligence, when they were sent to Mrs. Clinton in 2009 and 2011.

On Monday, the Clinton campaign disagreed with the conclusion of the intelligence review and noted that agencies within the government often have different views of what should be considered classified.

Mrs. Clinton’s work-related emails from when she was secretary of state are slowly being released by the State Department.
