WASHINGTON — The F.B.I. on Tuesday handed over to Congress documents related to its investigation of Hillary Clinton’s private email server after House Republicans pushed the bureau to surrender material it had gathered before it concluded last month that she should not face criminal charges.

The documents were believed to include notes from the F.B.I.’s 3½-hour interview with Mrs. Clinton in early July, the last step in a lengthy investigation into her email practices as secretary of state that continues to dog her run for president.

“The F.B.I. has turned over a ‘number of documents’ related to their investigation of former Secretary Clinton’s use of a personal email server,” according to a statement from the House Committee on Oversight and Government Reform. “Committee staff is currently reviewing the information that is classified Secret. There are no further details at this time.”
