There he goes again, exhibiting world-class boorishness before the entire world and embarrassing millions of Americans who have to live with the notion that he is our commander in chief.

He said the following today, through social media, of course, about the death of former FBI director Robert Mueller: Good, I’m glad he’s dead.

Mueller, appointed to lead the FBI by President George W. Bush and who served under President Barack Obama, died today of conplications from Parkinson’s disease. He was 81 years of age. Mueller served with distinction and high honor as a lawyer and then as FBI director, changing the agency’s mission to fighting terrorism in the wake of the 9/11 attacks.

He also led the investigation into allegations that Russia interfered with the 2016 presidential election. He determined the Russians did so but declined to prosecute the case because the evidence was lacking for a conviction. He drew Trump’s scorn throughout the probe.

Now this response to his death. Donald Trump once again has proven he is a disgrace to the nation.
