Heather Nauert, who earlier this year had been considered a possible successor to White House spokeswoman, Sarah Sanders, gained experience on diplomacy by working at the State Department, but she lacks the political and policy credentials of Ms Haley, who is a former governor of SC.
As reports broke Thursday night that former Fox News personality Heather Nauert could be in line to assume the role of United Nations ambassador and be named by Trump as early as Friday, not everyone was pleased.
The state department has made no comment.
Trump expected to pick State spokeswoman for UN ambassador
Numerous reports in the United States media - the first of which appeared in Bloomberg news - said Nauert would be nominated Friday, citing sources close to the matter.
If she wins Senate confirmation, Nauert will face a broad agenda at the United Nations topped by the need to maintain global sanctions on North Korea. President Donald Trump is expected to nominate Nauert to be the next USA ambassador to the United Nations.
According to multiple sources, the president will bring Heather Nauert from her current position as State Department spokeswoman to replace Haley at the United Nations.
Heather Nauert, a former anchor and correspondent at Fox News Channel, joined the State Department as spokeswoman in April 2017.
She will face a variety of challenges if confirmed for the job, including championing USA efforts to contain Iran's influence in the Middle East and ensuring the global body maintains tough sanctions on North Korea as Washington tries to negotiate an end to Pyongyang's nuclear and missile programs.
The Illinois native would follow in the footsteps of Haley, a former governor of South Carolina; Samantha Power, a Pulitzer Prize victor; Susan Rice, a Rhodes Scholar; and former National Security Council and national security officials such as Madeleine Albright.
She'll also take up the administration's efforts to defend Israel at the United Nations and counter what Haley called the organization's bias against the Jewish state. Trump is a regular viewer and one time guest of the show, and Nauert herself has developed a close relationship with Trump's daughter Ivanka.
Other candidates considered for the job, according to Bloomberg, were former White House adviser Dina Powell, ambassador to Canada Kelly Craft and ambassador to Germany Ric Grenell.
Israeli leaders nonetheless thanked her and feted the results as proof of wide support for Israel's position.
President Trump said she had done "an incredible job".
