Since installing themselves in Washington, Ivanka Trump and Jared Kushner have seen their horizons gradually shrink. Though both halves of the couple launched their neophyte political careers with sweeping goals and portfolios stuffed to bursting—Ivanka positioned herself as a champion of working women, while also inserting herself into conversations about human trafficking and climate change, and Jared was tasked with everything from overhauling the White House’s technology platforms to negotiating peace in the Middle East—the First Daughter has recently tried to tamp down on expectations, while her husband has reportedly seen his wings clipped by Donald Trump’s chief of staff, John Kelly.

Though her role as a diplomat has diminished accordingly—when her father traveled to Asia, Ivanka stayed behind to sell his tax plan—the First Daughter remains committed to a speaking engagement at the Global Entrepreneurship Summit in India, where she was invited by Indian Prime Minister Narendra Modi back in June. But according to CNN, Secretary of State Rex Tillerson is attempting to undermine her biggest gig yet representing America on the world stage, declining to send a delegation of State Department high-rollers to support her.

“They won’t send someone senior because they don't want to bolster Ivanka,” an unnamed senior State Department official told the network, adding that “No one higher than the deputy assistant secretary is allowed to participate. The secretary and his top staff have insisted on approving all travel—even the most minute details.”

A source close to the White House said that the smaller-than-usual delegation from State is by design, and is seen as a retaliatory move. “Rex doesn’t like the fact that he’s supposed to be our nation’s top diplomat, and Jared and now Ivanka have stepped all over Rex Tillerson for a long time,” the source said. “So now, he’s not sending senior people from the State Department to support this issue. He’s not supporting Ivanka Trump.” (A spokesperson for Ivanka declined to comment to CNN, and a State Department official said many State staffers will attend, but offered no explanation as to why no senior officials will be present.)

As the State Department source pointed out, the situation creates “another rift between the White House and State at a time when Rex Tillerson doesn’t need any more problems with the President.” Tillerson’s relationship with the First Family initially grew tense when he seemed to refute Trump’s statements following a violent white-nationalist rally in Charlottesville, and the situation only escalated with reports that the Secretary of State had privately called the president a “moron.” Amid growing rumblings that he would soon quit his job, Tillerson held a press conference wherein he told reporters, “I have never considered leaving this post.”

Nevertheless, Tillerson remains somewhat of an outlier in Trump’s cabinet, where according to my colleague Abby Tracy he routinely holes himself up in the State Department’s seventh-floor corridor of executive suites. But if he’s hoping to win a war of attrition against the Trump family, he may be in for a long winter. “We’re here to stay,” Kushner told the Washington Post on Saturday. “At the current moment, we’re charging forward.”
