The Trump-Comey saga continues this week after ousted FBI director James Comey reportedly declined to appear before the Senate Intelligence Committee in a closed meeting, insisting instead on a public hearing.

According to a “close associate” of Comey, who spoke with the New York Times, he was invited to provide civilian testimony on Tuesday but indicated his willingness extends only to an open setting. This news came amid a smattering of tweets by President Trump insinuating the White House might have recorded conversations between Comey and the president.

Tensions have risen after Trump relieved the former director of his duties this week, initially quoting his lack of trust in Comey after a mishandling of the investigation into Hillary Clinton’s emails last year.

The story has shifted, with Trump telling MSNBC’s Lester Holt on Thursday he had decided to fire Comey even before receiving a recommendation from the Department of Justice pointing to the Clinton ordeal as the reason for dismissal.

Trump’s decision to fire Comey initiated calls from both parties for a special prosecutor in the investigation of possible collusion between the Trump campaign and Russia, though no move in that direction appears forthcoming.
