On Monday, former Office of Government Ethics Director Walter Shaub tore into Senate Republicans for standing behind President Donald Trump in spite of all his attacks on the rule of law.

In particular, Shaub tweeted, Senate Republicans' refusal to exert any oversight in the wake of Trump firing the U.S. attorney for the Southern District of New York is a throwback to when every Senate Republican except Mitt Romney voted to fully acquit the president of abuse of power and obstruction of Congress in the Ukraine impeachment saga.

Shaub managed the White House ethics office in the first few months of the Trump administration, and resigned to work for the Campaign Legal Center after a series of clashes with administration and congressional officials.
