The FBI obtained a secret court order last summer to monitor the communications of an adviser to presidential candidate Donald Trump, part of an investigation into possible links between Russia and the campaign, law enforcement and other U.S. officials said.

The FBI and the Justice Department obtained the warrant targeting Carter Page’s communications after convincing a Foreign Intelligence Surveillance Court judge that there was probable cause to believe Page was acting as an agent of a foreign power, in this case Russia, according to the officials.

This is the clearest evidence so far that the FBI had reason to believe during the 2016 presidential campaign that a Trump campaign adviser was in touch with Russian agents. Such contacts are now at the center of an investigation into whether the campaign coordinated with the Russian government to swing the election in Trump’s favor.

Page has not been accused of any crimes, and it is unclear whether the Justice Department might later seek charges against him or others in connection with Russia’s meddling in the 2016 presidential election. The counterintelligence investigation into Russian efforts to influence U.S. elections began in July, officials have said. Most such investigations don’t result in criminal charges.

The officials spoke about the court order on the condition of anonymity because they were not authorized to discuss details of a counterintelligence probe.

During an interview with the Washington Post editorial page staff in March 2016, Trump identified Page, who had previously been an investment banker in Moscow, as a foreign policy adviser to his campaign. Campaign spokeswoman Hope Hicks later described Page’s role as “informal.”

Page has repeatedly denied any wrongdoing in his dealings with the Trump campaign or Russia.
