Though the message marks a departure from Trump’s more aggressive rhetoric about Muslims —Trump as a candidate spoke of establishing a registry of all Muslims in the United States, claimed that “Islam hates us,” and has sought to impose a travel ban on citizens of six Muslim-majority countries that the Fourth Circuit Court of Appeals said “drips with religious intolerance, animus, and discrimination”—it nonetheless signals a shift from the way the White House has traditionally commemorated the holiday.

Former President Bill Clinton, in his Ramadan address, spoke of the history behind the holy month and commended Islam’s teachings “of self-discipline, compassion, and commitment to family.” Barack Obama, in his final Ramadan message as president, acknowledged the Muslims who “may not be able to observe Ramadan from the comfort of their own homes this year” and reaffirmed the country’s commitment to welcoming immigrants and refugees.

Former President George W. Bush’s Ramadan message, delivered just months after the September 11 terrorist attacks, didn’t mention terrorism at all. Instead, it focused on the diversity within the American Muslim community, whose members “serve in every walk of life, including our armed forces.”

But perhaps the most notable difference between Trump’s statement and those of past presidents is not the overall theme of the greeting, but rather how it begins. “On behalf of all Americans,” the statement opens, “I would like to wish all Muslims a joyful Ramadan.” It frames the wishes as being delivered from “all Americans” to “all Muslims,” as though describing two distinct entities that don’t overlap. Though the president’s statement goes on to address the “many Muslims in America,” at no point are they referred to as “Muslim Americans” or as “American Muslims.”

As seemingly innocuous and perhaps unintentional as this wording may be, it could stand to upset the American Muslims who regard the president’s words as further proof of an administration that perceives Islam and its adherents as inherently antithetical to what it means to be American.

As more than three million American Muslims prepare to observe Islam’s most sacred month, which begins Friday at sundown, Secretary of State Rex Tillerson has reportedly declined to host a Ramadan event at the State Department—a tradition that’s been upheld by Republican and Democratic secretaries of state for nearly two decades. It remains unclear—and a subject of considerable speculation—whether Trump will continue the annual White House tradition of holding an Iftar dinner, the meal that marks the end of Muslims’ daily fast at sundown. Perhaps even more unclear is who would accept the invitation if he did.
