WASHINGTON: Federal government workers from the State Department to NASA are circulating open letters demanding that President Joe Biden pursue a cease-fire in Israel’s war against Hamas. Congressional staffers are picking up microphones in front of the Capitol, speaking out to condemn what they say is the silence of lawmakers about the toll on Palestinian civilians. As the deaths soar in Gaza, Biden and Congress are facing unusually public challenges from the inside over their support for Israel’s offensive. Hundreds of staffers in the administration and on Capitol Hill are signing on to open letters, speaking to reporters and holding vigils. “Most of our bosses on Capitol Hill are not listening to the people they represent,” one of the congressional staffers told the crowd at a protest this month.
