Former Bush AG: Wiretap would mean suspicion of someone acting as Russian 'agent'

Michael Mukasey was attorney general for former President George W. Bush.

Raddatz, on ABC's "This Week" on Sunday, asked Mukasey the basis for his view.

Schiff, a California Democrat, is the ranking member of the House Intelligence Committee, and has been critical of the FBI’s cooperation with the committee’s investigation into Russia’ interference in the 2016 election, saying in a statement Sunday, “If the Administration truly believes that President Obama illegally eavesdropped on the Trump campaign and wants our committee to investigate the matter, they should join my call on Director Comey to answer any question put to him that is pertinent to the Russia investigation."

On "This Week," Raddatz noted that the FISA court would have approved a wiretap only if there was evidence for suspicion."So, if there was a wiretap, does that mean there were suspicious things going on between the Trump administration and the Russians?" she asked.

"It means there were some basis to believe that somebody in Trump Tower may have been acting as an agent of the Russians, for whatever purpose, not necessarily the election, but for some purpose," Mukasey said.

When Clapper was asked whether he could confirm or deny the existence of a FISA court order to wiretap Trump Tower, he said, "I can deny it," adding that such surveillance is "absolutely" information he would have been told about as director of national intelligence.
