A Facebook spokesman said that the company was able to receive the letter and that they will be reviewing the questions.

The report regarding Facebook's "Trending Topics" section was placed on the spotlight on Monday after an article was published by Gizmodo.

However, Tom Stocky, the vice president of search in Facebook, released a statement saying that his team was not able to find any evidence supporting the claims of Gizmodo. Facebook added that workers on the "Trending Topics" feature are not allowed to suppress particular news outlets or topics as there are technical blockers.
