A question for Robert Mueller

House Democrats have delayed former special counsel Robert Mueller’s Capitol Hill testimony until July 24 to allow for “expanded questioning.”  By this they mean grandstanding, virtue signaling, political posturing and contriving theatrical stunts aimed at resuscitating the discredited “obstruction” claims against President Trump.

The question remains why Mueller should testify at all. There is no chance that he will add anything of substance to the matters already amply explored in the 448-page report on his two-year investigation. There will be no new evidence, no smoking gun, nothing to clarify what has already been made quite clear: there was no collusion, no obstruction.

But clarity is hardly the objective in this political circus. Democrats are bound and determined to muddy the waters to resuscitate the comatose impeachment narrative. And Mueller may be more than willing to help.
