(The Hill) The FBI used the dossier alleging Russian ties to President Trump’s campaign associates to help convince a judge to grant a warrant to secretly monitor former campaign aide Carter Page, CNN reports.

FBI Director James Comey has cited the dossier in some of his briefings with lawmakers in recent weeks as one of the information sources used by his bureau to bolster its probe, U.S. officials briefed on the investigation told CNN.

The FBI is investigating Russian efforts to interfere in the 2016 election, as well as any potential ties between the Trump campaign and Moscow.

The secret court that oversees the Foreign Intelligence Surveillance Act (FISA) granted the FBI a warrant to monitor the communications of Page, a former national security adviser on Trump’s campaign.

The FBI obtained its warrant to monitor Page in the summer of 2016, The Washington Post reported last week.

Page has denied any wrongdoing since news of the warrant last week and has dismissed reports that he provided a Russian operative with classified information.
