I'll give you a nice citation (not the one you were hoping for, though), as soon as the actual tape, not the InJustice Department redacted abstract, of the call with the president of Ukraine is released and transcribed. That's only one rope your Dear Leader can be strung up with; more to come as improperly classified records are released. Or we could debrief the silenced translators from Trump's several closed-door meetings with the nation's number one enemy. A veritable treasure trove that will be giving gifts for decades to come, and supplying many a budding historian with his/her Pulitzer material.
