Newly disclosed emails show top Obama administration officials were in close contact with Hillary Clinton’s nascent presidential campaign in early 2015 about the potential fallout from revelations that the former secretary of state used a private email server.

Their discussion included a request from the White House communications director to her counterpart at the State Department to see if it was possible to arrange for Secretary of State John Kerry to avoid questions during media appearances about Mrs. Clinton’s email arrangement.

In another instance, a top State Department official assured an attorney for Mrs. Clinton that, contrary to media reports, a department official hadn’t told Congress that Mrs. Clinton erred in using a private email account.

The previously unreported emails were obtained by the Republican National Committee as part of a Freedom of Information Act lawsuit seeking records of Mrs. Clinton’s time in office.
