Another State Department official, the highest ranking so far, has resigned in the months succeeding the beginning of the war in Gaza between Israel and Hamas.

Andrew Miller, the department’s deputy assistant secretary for Israeli-Palestinian affairs, told coworkers Friday that he would be resigning from his post, citing family obligations, according to the Washington Post. While not specifying the policy on Israel and Gaza as the motivating factor for leaving, the report suggested that he was a supporter of Palestinian statehood.
