President Donald Trump on Friday shed new light on why he apparently bluffed about having recordings of his conversations with former FBI Director James Comey, suggesting for the first time that a Twitter post about “tapes” was meant to influence Comney’s public comments about his firing. In the interview that aired Friday morning on Fox News, Trump indicated that, by threatening to release recordings of their encounters, he was trying to make sure Comey was honest about what they had discussed.
