New York (CNN Business) A Facebook executive who backed Hillary Clinton's 2016 election campaign told colleagues in an internal memo last month that the platform could ultimately be responsible for President Trump's reelection.

In the memo, Facebook VP Andrew Bosworth wrote that the Trump campaign's use of Facebook's advertising tools were responsible for Trump's win in the 2016 presidential election. The company's political advertising platform, he added, "very well may lead to the same result" this year.

"As a committed liberal I find myself desperately wanting to pull any lever at my disposal to avoid the same result," Bosworth said in the memo. But he laid out his philosophical objections to any theoretical attempt at intervening. "As tempting as it is to use the tools available to us to change the outcome, I am confident we must never do that or we will become that which we fear."

The memo was first reported Tuesday by The New York Times . Soon after, Bosworth posted the memo to his public Facebook profile, noting that "it wasn't written for public consumption."

Bosworth, a longtime Facebook executive and confidant of CEO Mark Zuckerberg, used the memo to dismiss filter bubbles ("a myth" that distracts from the real issue of polarization), explain why Facebook is more like sugar than nicotine ("It benefits from moderation") and offer his analysis of the platform's real impact on the 2016 election.
