Hicks, 29, is best known as one of President Donald Trump's most trusted aides. In her testimony, Hicks admitted telling occasional "white lies" for Trump but said she hadn't lied about anything related to the investigation. The company, which will still control the Fox broadcast network and the Fox News Channel, is expected to focus on live sports, news and the local TV business.
The relationship between between the White House and the Fox empire is well documented. Her new role will give her power in an amorphous media company, figuring out an identity after selling off numerous products for which it is best known.
At New Fox, Hicks will succeed two executives who oversaw 21st Century Fox's communications when Fox News was beset by multiple sexual harassment allegations, including against its co-founder Roger Ailes and top star Bill O'Reilly.
She will be based in Los Angeles.
In July, Disney outbid Comcast Corp with a $71.3 billion offer to buy some assets from Fox. "Together they will define and project Fox's voice to our relevant communities", Dinh told Variety.
Dinh announced her appointment Monday, along with that of Danny O'Brien, a former senior government affairs and policy executive from General Electric, who will become Fox's EVP and head of government relations. O'Brien previously served as chief of staff to Senators Joe Biden (D-Del.), Robert Menendez (D-N.J.) and Robert Torricelli (D-N.J.).
