Here's everything you need to know about Hurwitz:
Who Is She?
Sarah Hurwitz currently serves, according to the White House, as senior advisor to the White House Council on Women and Girls.
Like her boss, Hurwitz is a Harvard graduate, receiving her law degree from the school as well.
What's She Written Before?
Hurwitz was the writer behind the Clinton's concession speech in 2008, which is best known for the line in which she said her supporters made “18 million cracks” in the glass ceiling.
According to the Washington Post, Hurwitz is "one of the few remaining staff members who joined the White House straight from the 2008 campaign. She started that cycle, though, as Hillary Clinton’s chief speechwriter. Two days after Clinton conceded defeat with a memorable speech hailing '18 million cracks' in the 'highest, hardest glass ceiling,' the Obama team called to offer Hurwitz a job."
Hurwitz then went on to write Michelle Obama's 2008 convention speech, the one Melania Trump is accused of lifting lines from for her own convention speech.
How Did Michelle Obama's DNC Speech Come Together?
The New York Times reports that Monday night's speech went through several drafts.
"They met in the first lady’s East Wing office with other top aides to go over Mrs. Obama’s edits, handwritten in the margins of the drafts or sent to the group in an email," the New York Times reported.
The powerful speech became one of the top three most mentioned moments from the convention Monday.
And, after President Obama tweeted his congrats, his heartfelt praise became most re-tweeted tweet of the day, with 120,000-plus sharing his words.
The DNC runs through Thursday.
