First daughter and White House senior adviser Ivanka Trump shut down any speculation that she might be chosen to replace outgoing United Nations Ambassador Nikki Haley with a tweet Tuesday.

“It is an honor to serve in the White House alongside so many great colleagues and I know that the President will nominate a formidable replacement for Ambassador Haley,” Trump said hours after it was revealed Haley would depart her post at the end of the year. “That replacement will not be me.”
