I wonder why Trump is so afraid to allow his people, who presumably would provide exculpatory testimony on his behalf, to testify. Could it be that, under oath and with the possibility of a conviction for lying to Congress — witness Mr. Roger Stone — hanging over their heads, those folks would only corroborate the testimony that was previously given by those who did appear, thus solidifying the case for impeachment? If the president has done nothing wrong, as he continues to claim, why does he continue to stonewall? That, to me, is an indication of guilt. Let the truth, whatever it might be, come out, and then let Congress decide if he deserves to remain in office or be kicked out in disgrace.
