WASHINGTON (AP) — An Interior Department staffer on Wednesday became the first Jewish political appointee to publicly resign in protest of U.S. support for Israel’s war in Gaza.

Lily Greenberg Call, a special assistant to the chief of staff in the Interior Department, accused President Joe Biden of using Jews to justify U.S. policy in the conflict.

Call had worked for the presidential campaigns of both Biden and Vice President Kamala Harris, and was a longtime activist and advocate for Israel in Washington and elsewhere before joining the government.

She is at least the fifth mid- or senior-level administration staffer to make public their resignation in protest of the Biden administration’s military and diplomatic support of the now seven-month Israeli war against Hamas. She is the second political appointee to do so, after an Education Department official of Palestinian heritage resigned in January.
