U.S. Muslim advocacy group Emgage Action on Wednesday endorsed Democratic presidential candidate Kamala Harris despite its ongoing concern over the war in Gaza, saying former President Donald Trump posed a greater danger with his promise to reinstate travel restrictions affecting majority-Muslim countries.

The endorsement comes as the 2024 race between Harris and Trump remains very tight ahead of the Nov. 5 election. Arab American and Muslim voters may play a decisive role in the outcome in Michigan, Pennsylvania, Georgia and other battleground states. These voters helped President Joe Biden defeat Trump in 2020 by thousands of votes.

Many Muslim groups, including Emgage Action, have criticized the Biden administration, where Harris serves as vice president, for its support of Israel's war in Gaza. Harris has urged an immediate ceasefire and hostage release deal in Gaza, saying she supports Israel's right to defend itself as well as the Palestinians' right to self-determination.

"While we do not agree with all of Harris’ policies, particularly on the war on Gaza, we are approaching this election with both pragmatism and conviction," Emgage CEO Wa'el Alzayat said in a statement, adding it sought to provide "honest guidance to our voters regarding the difficult choice they confront at the ballot box."

Emgage Action, which endorsed Biden in 2020, said it mobilized 1 million Muslim voters in that election. The group said the Harris endorsement reflects a "responsibility to defeat Trump and defend the community against what would be a return to Islamophobic and other harmful policies."

Trump's campaign had no immediate comment.

His campaign has held dozens of events with Arab Americans and Muslims in swing states and plans another event this weekend in Michigan, Richard Grenell, Trump's former acting director of national intelligence, said last week.

Trump has said he will reinstate the "travel ban" that restricts entry into the United States of people from a list of largely Muslim-dominant countries. Biden rolled back the ban shortly after taking office in 2021.

The Harris campaign welcomed the endorsement a week after another big voting bloc, the pro-Palestinian grassroots organization Uncommitted National Movement, said it would not endorse Harris, Trump or a third-party candidate.

Harris has already won the backing of smaller Muslim groups, including the Black Muslim Leadership Council Fund and the American Muslim Democratic Caucus.

The U.S., Israel's biggest ally and weapons supplier, has sent Israel more than 10,000 highly destructive 2,000-pound (900-kg) bombs and thousands of Hellfire missiles since the start of the Gaza war in October, U.S. officials told Reuters in June.

The war in the Gaza Strip began on Oct. 7, 2023, when Hamas gunmen stormed into Israeli communities, killing some 1,200 people and abducting about 250 hostages, according to Israeli tallies.

Since then, Israel's military has levelled swaths of Gaza, driving nearly all of its 2.3 million people from their homes, giving rise to deadly hunger and disease and killing more than 41,000 people, according to Palestinian health authorities.
