In November 2016, I questioned whether Republicans who investigated the Obama administration with passion would do their job as a check on the president.

“Many Republicans are more concerned about excusing Trump’s abuses of power than investigating them,” I wrote.

We’ve seen their performance for one year. How have they done? There are token efforts in the House and a somewhat more critical effort in the Senate to look into the Russian controversies. The Republicans haven’t even lifted a finger to investigate Trump’s conflicts of interest as owner of a vast business network, including a DC hotel where foreign diplomats like to stay.

But there have always been a Trumpist Republicans eager to run interference for their guy. Rep. Devin Nunes met with the White House to coordinate talking points this spring. Now Nunes and other Republicans are using their powers to try to undermine the FBI. Rep. Matt Gaetz called for firing Mueller.

Attacks on Special Prosecutor and Republican Party member Robert Mueller have been picking up in recent weeks. Republicans have just held an investigatory session of FBI Director Andrew McCabe, and asked seemingly tougher questions than they ask of Trump’s allies.

The Trumpist wing of the right-wing media is picking up any and every straw they can find to try to undercut the investigation. The conservative wing of the right-wing media is often downplaying or ignoring revelations.

Meanwhile, Republicans are pushing harder and harder for Trump to investigate people who aren’t in power, like Hillary Clinton. Department of Justice director Jeff Sessions, after being pushed by Republicans to pick a Special Council to investigate Clinton, has “begun asking FBI agents to explain the evidence they found in a now dormant criminal investigation into a controversial uranium deal that critics have linked to Bill and Hillary Clinton, multiple law enforcement officials told NBC News.”

The idea for many Republicans seems to be to be a check (or even obstructionists) on watchdogs like the FBI and defeated politicians like Clinton and a guarddog on power.
