Vivian Schiller is stepping down from her position as the head of news for Twitter amid management reorganization.

Schiller, a veteran executive in news positions, joined Twitter as its head of news less than a year ago. Her role was to oversee the social network's partnerships with organizations focused on news and journalism.

Schiller announced her resignation from the position to the public in a series of tweets under her account, similar to what Chloe Sladden, Schiller's former boss as vice president of media, did when she left Twitter in June.

"Stepping down from Twitter so new global media lead @katies can reorganize as she sees fit. Wish everyone at twitter nothing but best," tweeted Schiller in the first of three tweets of her announcement.

Schiller was referring to Katie Jacobs Stanton, her new boss and currently Twitter's global media chief.

To replace Schiller, Stanton has appointed Adam Sharp to head news and government partnerships, which was the position that he previously held before Schiller was recruited to Twitter by former Twitter COO Ali Rowghani and Sladden.

Sharp, a former Senate aide and C-Span executive, has assisted several politicians in figuring out how to utilize Twitter to further their campaigns. With Sharp's return to his former role, he will be tasked to do the same thing, but this time including news organizations. He will be reporting to Kirstine Stewart, former Canadian Broadcasting Corporation executive and who recently transferred from Twitter Canada to take over the position left open by Sladden's departure.

However, Sharp's role can be seen as a highly conflicted one, as he will be tasked to advise both politicians, who look to influence the opinion of the public, and journalists, who wish to see beyond the influences to be able to discern the facts and write an unbiased story.

Schiller's departure is the latest of a series of resignations following clashes between Rowghani and Twitter CEO Dick Costolo over whether Rowghani should continue to oversee the product development for the social network.

Rowghani resigned shortly after the disagreement with Costolo, followed by Sladden a few hours later.

Rowghani and Sladden recruited Schiller to Twitter, who brought an impressive resume with her to the social network. She was the first chief digital officer for NBC News and the chief executive of NPR, which is formerly known as National Public Radio. Schiller also used to be the head of CNN Production and led operations at the news website of the New York Times.
