One hallmark of the presidency of Donald Trump is his reaction to anyone who criticizes him, disagrees with him or fails to praise him sufficiently.

Name calling, bullying and general pettiness is how Trump routinely responds.

So Wednesday's reaction to news regarding the health of the only GOP Senator to vote for Trump's conviction—Utah's Senator Mitt Romney—was pretty standard fair.

Right wing publication Breitbart shared news that despite being one of the Senators exposed to the virus behind the current public health crisis, Romney tested negative. Trump retweeted Breitbart's post on Twitter.

Trump captioned the retweet:

"This is really great news!"

"I am so happy I can barely speak."

"He may have been a terrible presidential candidate and an even worse U.S. Senator, but he is a RINO, and I like him a lot!"

RINO is the term coined by Tea Partiers for Republicans In Name Only.

People failed to find the humor in the presidential pettiness.

Some critiqued Trump's response to the global pandemic.

They also gave Trump a failing grade for his attempt at sarcasm.

Romney announced his decision to self-quarantine after Republican Senator Rand Paul of Kentucky made the choice to expose all of hi, colleagues to the virus he had been exposed to at a GOP fundraiser. Paul tested positive six days after his exposure.

Despite testing negative, Romney vowed to continue to self-isolate for the remainder of the 14 days according to CDC and WHO guidance.
