On 'Tucker Carlson Tonight,' the Fox News host discusses the Durham investigation.

A Justice Department filing says Hillary Clinton's presidential campaign paid a technology company to "infiltrate" Trump Tower servers, and later the White House. The purpose of the infiltration was to establish a "narrative" of collusion between then-Republican presidential candidate Donald Trump and Russia. Tech Executive-1 enlisted the help of researchers at a U.S.-based university to mine Internet data for derogatory information about Donald Trump, according to newly filed court documents. Former Attorney General William Barr appointed former FBI agent David Durham to investigate the origins of the FBI's Russia probe.
