Fowl play

In case anyone had any remaining doubts, Trump is demonstrably guilty of obstructing justice. Trump just pardoned the Thanksgiving turkey. 

Presidential pardons can be abused to buy the silence of potential accusers. The turkey was a potential witness in the Russian collusion investigation. Mueller indicted the turkey to put the squeeze on the ill-fated fowl. Nothing loosens the tongue of a gallinaceous witness for the prosecution like the prospect of winding up on a dinner platter. Anonymous informants at the DOJ tell me that the stressed-out Galliforme was on the verge of turning state's evidence against Trump when he pardoned it, thereby robbing Mueller of his star witness.
