Vice President Mike Pence attends an event where Melania Trump spoke in the Rose Garden of the White House May 7, 2018 in Washington, DC.
Scarborough theorized that Pence might not be revealing all that he knows about the investigation, particularly about former national security adviser Michael Flynn.
He continued: "Nor any mention, by Vice President Pence, of the five guilty pleas, one person sentenced, 23 defendants and 75 criminal charges in all Robert Mueller's investigation has yielded so far".
President Donald Trump has continually called Mueller's sprawling investigation a "witch hunt" and denied any "collusion" with Russian entities regarding the 2016 campaign.
"Namely, do they have an open mind to the fact he could be telling the truth and Comey may be lying?"
Last week on ABC, Giuliani said he can't be "confident" Trump would not refuse to answer questions on the his absolute Fifth Amendment right to avoid incriminating himself.

Trump announced Thursday that his high-profile summit will take place next month in Singapore with North Korean leader Kim Jong Un.
