A congressman who attended Harvard at the same time as Mark Zuckerberg accused the Facebook co-founder of “rewriting history” amid an ongoing whirlwind over the social media giant’s declaration that it will not police political speech, even if it contains outright lies.

Rep. Ruben Gallego (D-Ariz.), a former Marine Corps reservist who served in Iraq, made the comments on Tuesday after Zuckerberg’s address at Georgetown University last week. During the event, Zuckerberg cited the Iraq War as at least partially responsible for his decision to create Facebook and defended the company as a bastion of free speech.

“I remember feeling that if more people had a voice to share their experiences, maybe things would have gone differently,” the Facebook co-founder said Thursday. “Those early years shaped my belief that giving everyone a voice empowers the powerless and pushes society to be better over time.”

But those remarks puzzled Gallego and others who were at Harvard during the social media network’s early years, after it was spawned from a website created to rank college students based on attractiveness. They said the earliest versions of Facebook didn’t even allow users to communicate with each other or debate political issues.

“I was the only reservist on the campus and was keenly aware of the Iraq Debate on campus,” Gallego, who said he had one of the “first” Facebook accounts, wrote Tuesday. “This is no where near the truth, it was designed to be [an] easier cleaner MySpace based off our House books.”
