Amer Ghalib has made a lot of national news as the leader of a small, Midwestern city.

His election in 2021 as mayor of Hamtramck, Mich., was itself a headline. Mr. Ghalib, who is from Yemen, became the first Arab American and first Muslim to govern the city. And he was working with what was believed to be the first all-Muslim City Council in the country.

Two years later, Mr. Ghalib created another stir when he and other socially conservative Muslims banned the L.G.B.T.Q. Pride flag from publicly owned flagpoles, alarming liberals who said the move was discriminatory and harmful to the city’s welcoming reputation.

Their fears only heightened last month, after Mr. Ghalib endorsed Donald J. Trump, who as president had ushered in what is known as the Muslim ban, blocking immigrants from seven majority-Muslim nations, including Mr. Ghalib’s home country. Adding to the tensions was a visit by Mr. Trump, who hoped the mayor’s support could peel off a meaningful number of Muslim voters in Michigan, a swing state.

Explaining his support, Mr. Ghalib pointed to a distaste for liberal social views, anger at President Biden’s support of Israel and a belief that Mr. Trump will end the conflict in the Middle East.
