Carter Page
Carter Page is an American petroleum industry consultant and a former foreign-policy advisor to Donald Trump during his 2016 presidential election campaign.
Mr. Page was a focus of the 2017 Special Counsel investigation into links between Trump associates and Russian officials and Russian interference on behalf of Trump during the 2016 presidential election. In April 2019, the Mueller Report revealed that investigators found no direct evidence that Page coordinated Trump campaign activities with the Russian government.
In 2019 the Justice Department determined the last two of four FISA warrants to surveil Page were invalid.
