FBI officials have interviewed former Trump campaign adviser Carter Page for more than ten hours about his ties with Russia, The Washington Post reports. The interviews took place over five meetings in March, before special counsel Robert Mueller began investigating the Trump campaign's Russia dealings. Page has reportedly been under FBI surveillance since last summer, under suspicion that acted on behalf of Russian intelligence. During the March interviews, FBI officials reportedly questioned Page on a dossier that described him meeting with two Kremlin officials in July 2016. Page denied having attended the meetings.
