Threatening to withhold contributions and votes in favor of President Joe Biden’s 2024 reelection, certain Muslim and Arab American groups are pressing him to act quickly to ensure a ceasefire in Gaza.

The National Muslim Democratic Council, which is made up of Democratic Party officials from states like Michigan, Ohio, and Pennsylvania that are in close contests and have the power to decide elections, asked Biden to use his connections with Israel to mediate a ceasefire by Tuesday at 5 p.m. ET (2100 GMT).

In an open letter entitled “2023 Ceasefire Ultimatum,” Muslim leaders pledged to mobilize “Muslim, Arab, and allied voters” to “withhold endorsement, support, or votes for any candidate who endorses the Israeli offensive against the Palestinian people.”

“Your administration’s unconditional support, encompassing funding and armaments, has played a significant role in perpetuating the violence that is causing civilian casualties and has eroded trust in voters who previously put their faith in you,” the council wrote.
