In 1993, Page graduated from the US Naval Academy. He served in the Navy for five years before working on arms control at the Pentagon and moving to New York for a fellowship at the Council on Foreign Relations.

After working as an investment banker at Merrill Lynch in London, Page moved to its Russia branch, where he was a vice president from 2004 to 2007.
While in Russia, Page developed relationships with Russian oil executives, especially from the Kremlin-connected company Gazprom.

While Page has touted his credentials as an expert on the Russian energy market, a handful of other experts in the field told Politico they denied even knowing who he was.

"Strangely I've never heard of Carter Page until this Trump connection," Bill Browder, an American investor who spent years working in Russia, told Politico. "It's odd because I've heard of every other financier who was a player in Moscow at the time."

Over the course of his career in foreign policy, Page has not shied away from criticizing what he has described as US hypocrisy toward Russia. According to The Washington Post, Page has praised Putin as a better leader than former President Barack Obama.

"Washington and other Western powers have impeded potential progress through their often hypocritical focus on ideas such as democratization, inequality, corruption and regime change,” Page said during a speech in Moscow in front of prominent Russian government officials.

Over the years, Page's dealings in Russia caught the attention of US government officials, who suspected that he may be working as an agent of Moscow. Intelligence officials knew of him as far back as 2013, well before he joined the Trump campaign.

During the 2016 election campaign, Trump announced that Page was one of his foreign policy advisers.

But controversy ensued over Page's role in the campaign when the FBI launched its probe into whether Trump or his associates were colluding with Russia to influence the election.
Last November, Page testified before the House Intelligence Committee. In that testimony, he confirmed meeting Russian government officials during a trip to Moscow during the US presidential campaign. Page denies any wrongdoing or improper dealings with Russia.

In January, Page became the subject of controversy when Republicans alleged in a memo that officials at the FBI and the DOJ misled a federal judge who authorized surveillance on Page before and after the 2016 campaign.

On Friday, Trump released that memo, despite objections from Democrats and senior law-enforcement officials, including the director of the FBI.
