Just moments after Comey’s prepared opening remarks to the Senate Intelligence Committee were posted to the United States Senate website, Vice President Mike Pence abruptly canceled a planned interview with PBS Newshour.

“Moments ago, @VP Pence cancelled a scheduled interview with @newshour,” Sara Just, , the show’s executive producer, tweeted Wednesday.

No explanation for the cancelation was given, despite the fact that the interview had already been promoted on the air on Tuesday.

The announcement came as a surprise to PBS correspondent Miles O’Brien, who was already at Johnson Space Center in Houston, Texas, to interview the vice president.

Pence’s cancellation came shortly after former FBI Director James Comey made public his prepared opening remarks ahead of his scheduled testimony to Congress on Thursday.

Among other things, Comey’s explosive remarks confirm earlier media reports that Trump pressured him to “let go” of the bureau’s investigation into ousted national security adviser, Michael Flynn.

Comey will also testify that Trump asked him to ‘get out’ that he is not personally under investigation” for possible collusion with Russia.
