Since his installation, Barr has engaged in flagrant, serial obstructions of justice. It continues, in plain sight. Proving the crime of obstruction of justice under 18 U.S. Code § 1503(a), however, will be a tall order.
It will need indisputable evidence of corrupt intent similar to that which put John Mitchell away. In Barr's case, the *pattern* of his obstructive acts will be a key factor in showing intent.
Every time he pushes against a valid investigation of Trump or associates, Barr adds to the pattern, and increases his exposure. This will not be settled before the election, but will be an urgent matter for the Biden administration.
I would urge Biden to put the focus strongly on Barr's criminal activity, now, calling it what it is (obstruction of justice), and giving fair warning to the electorate that the Biden administration will carefully investigate the validity of criminal charges against Barr.
