I'm ready and prepared, Leavitt answers on the Trump-friendly TV channel
when asked how it feels to enter the "hostile territory" that the White House press corps can constitute.
It's likely an honest answer. Over the past year, she has been the Trump campaign's press secretary and handled countless requests and interviews.
False news?
Despite her young age, Leavitt has also run a campaign (although lost) to become a representative from her home state of New Hampshire, and worked at the White House press department during Trump's first term. This summer, she gave birth to a son.
Like her boss, she doesn't hesitate to use expressions like "false news" and has referred to The Washington Post as "The Washington Compost".
They have printed lies and deceit about him for eight years, and his words are constantly taken out of context, she says to Fox News about traditional media.
But she also says that she wants to maintain the dignity of the press room and is open to letting "new media" like podcasts sit in the front rows.
Smart and tough
The US's future president has called the press "the people's enemy". After the assassination attempt on him this summer, he said it wouldn't matter if future would-be murderers shot through "false news (corps)", as Vanity Fair reminds us.
Leavitt and he have very good chemistry, according to sources. In the appointment, Trump describes her as "smart and tough".
