Within moments of news breaking that United Nations Ambassador Nikki Haley was resigning, speculation roared about whether President Trump would pick his daughter and White House adviser Ivanka Trump to fill the role.

CNN anchor Poppy Harlow floated the possibility at least twice on air Tuesday morning, noting that whoever replaces Haley would need to have “strong relationships” with lawmakers from both parties.

“I do think she may have some interest in a role like this that would truly put her on the world stage and put her focus on some more of the global issues where she may be able to have some success,” Harlow said.

“There’s been talk about how her and her husband would like to get back to New York,” CNN political analyst Mark Preston said. Trump and her husband, Jared Kushner previously lived in New York City before moving to Washington to work in the White House.

Conservative commentator Ann Coulter, who has been critical of Trump’s family serving in the administration, backed the president appointing his daughter to the position.

Others, including Mother Jones' David Corn and MSNBC's Mika Brzezinski, also brought up the possibility.

The New York Times reported in November 2017 that Ivanka Trump and Kushner had considered a scenario “in which Ms. Trump could replace Nikki R. Haley as ambassador to the United Nations if Ms. Haley replaced Secretary of State Rex. W. Tillerson.”

In remarks to the press in the Oval Office on Tuesday, Haley called Ivanka Trump, who was present in the room, “a great friend.”

Twitter users were also quick to note that Trump Alert, a bot that tracks Twitter activity by the Trump family, shared the fact that Ivanka Trump followed several Defense Department-related Twitter acounts on Monday.

Ivanka Trump praised Haley as having served her country with "dignity" and "distinction."

"She is a bold reformer and has been an unwavering champion of truth, principled realism and integrity within the United Nations. Jared and I are grateful for her friendship — a true blessing in our lives!" she wrote in a tweet.
