Mrs. Clinton’s presidential campaign, which has been shadowed for 17 months by the controversy over the private email server she used exclusively while at the State Department, said that the emails released Tuesday had no bearing on the foundation’s work.

The State Department turned the new emails over to a conservative advocacy group, Judicial Watch, as part of a lawsuit that the group brought under the Freedom of Information Act.

The documents included 44 emails that were not among some 55,000 pages of emails that Mrs. Clinton had previously given to the State Department, which she said represented all her “work-related” emails. The document release centers on discussions between Mrs. Clinton’s aides and Clinton Foundation executives about a number of donors and associates with interests before the State Department.

Tom Fitton, the president of Judicial Watch, charged that Mrs. Clinton “hid” the documents from the public because they appeared to contradict her official pledge in 2009 to remove herself from Clinton Foundation business while leading the State Department.

The documents indicate, he said in a telephone interview, that “the State Department and the Clinton Foundation worked hand in hand in terms of policy and donor effort.”
