Jonathan Turley, professor of constitutional law at George Washington University, was called by Republicans to testify on the legal grounds for impeachment last week. He writes that Democrats have made an underwhelming case for removing a president.

For three years, Democratic members have pledged to unleash the dogs of impeachment to devour a president despised by their base.

Today, the doors finally opened and the public found itself staring not at a multi-headed Cerberus from Hades, but a couple of underfed chihuahuas.

In my testimony before the House Judiciary Committee last week, I focused on the crimes like bribery that Speaker Nancy Pelosi and House Intelligence Committee Chairman Adam Schiff declared repeatedly were now well-established.

Those claims were legally unfounded and untenable, though the other witnesses and members vociferously insisted that they were clear and established.The response was all too familiar.

For three years, the same Democratic leadership told the public that a variety of criminal and impeachable acts were proven in the Mueller investigation. None of those crimes are now part of this impeachment. Why? Because it would have been too easy an impeachment?

Instead, the House will go forward on the only two plausible grounds that I outlined in my testimony: abuse of power and obstruction of Congress.

Unlike the other claims, the problem is not with the legal basis for such impeachable offenses but the evidentiary record. This record remains both incomplete and conflicted. The Democrats have insisted on impeaching by Christmas rather than build a record to support such charges.

This is now the fastest investigation with the thinnest record supporting the narrowest impeachment in modern history. It is precisely what President Trump (who not surprisingly has supported the Democratic move for a fast impeachment) would relish.

The Democrats just gave him the best Christmas gift he could hope for. Two chihuahuas with barely the energy to make the walk over to the Senate.
