There was a point in the Barr confirmation hearings where it would have been a scandal if Barr had admitted that the "president" had urged him to investigate a political rival (remember Harris' question, which Barr evaded?)
Now we know that Trump was urging a foreign country to investigate a political rival and he was offering the help of Barr, now fully confirmed Attorney General of the United States of America, and Barr's DOJ did its best to keep that fact from the public. The response from Republicans are all smiley face shrug emoji.
This is a reminder that Republicans thought it was a huge scandal when Bill Clinton had a five minute conversation with then attorney general Loretta Lynch on a tarmac between flights. So much so that she recused herself from the Emails matter.
No sign yet that Barr will be recusing himself from anything regarding Ukraine.
