NEW YORK - New York City Mayor Bill de Blasio's press secretary is set to resign after slightly more than one year on the job.

An administration spokesman confirmed Thursday that Karen Hinton submitted her resignation last month.

She is expected to leave her post by the end of June, at the conclusion of the current city budget negotiations.

Hinton, in a statement, said she it was "a privilege" to work for de Blasio, a first-term Democrat.

Her resignation comes at a politically perilous time for de Blasio, whose administration is at the center of a federal and state investigation into its campaign finance practices.

Administration officials said her departure - which was first reported by The New York Times - was unconnected to the probe.
