UPDATE
A source close to the situation said Brazile will not have anything to do with the debate or town hall process.

She emphasized these points in a new op-ed for Fox News.
"My decision to serve as a commentator for Fox News is rooted in the belief that you cannot make progress, let alone reach compromise, without first listening to, and understanding those who disagree with you on critical issues," she writes.

Brazile adds that of course there will be tension, but it's healthy for debate.
Will I agree with my fellow commentators at Fox News? Probably not. But I will listen.
Will I question them if they make assertions about hard-working Americans, low-income people and issues like climate change that I disagree with? Absolutely. But I will do so with civility and respect. I will also freely admit the weaknesses in liberal arguments and the strength in conservative positions. And I welcome the opportunity to challenge many of the false assumptions about progressives, especially those newly elected to Congress.
Brazile infamously wrote a book called Hacks: The Inside Story of the Break-ins and Breakdowns That Put Donald Trump in the White House, in which she exposed the DNC's cozy relationship with the Hillary Clinton campaign (to the detriment of Bernie Sanders) and the committee's financial incompetence.
The bias she witnessed "broke her heart," she revealed at a talk in Washington, D.C.
Brazile's announcement comes just days after current DNC Chair Tom Perez revealed that the committee will not be partnering with Fox for the 2020 debates.
She will make her first appearance on Fox News on The Daily Briefing with Dana Perino at 2 p.m. ET today.
