Too stupid to understand how it would look

From the Washington Post, there's a recurring theme of "anger" in this story.  (These are various extracts from the report):

Trump was angry that Comey would not support his baseless claim that President Barack Obama had his campaign offices wiretapped. Trump was frustrated when Comey revealed in Senate testimony the breadth of the counterintelligence investigation into Russia’s effort to sway the 2016 U.S. presidential election. And he fumed that Comey was giving too much attention to the Russia probe and not enough to investigating leaks to journalists....

In his Tuesday letter dismissing Comey, Trump wrote: “I greatly appreciate you informing me, on three separate occasions, that I am not under investigation.” People familiar with the matter said that statement is not accurate, although they would not say how it was inaccurate. FBI officials declined to comment on the statement, and a White House official refused to discuss conversations between Trump and Comey....

The media explosion was immediate and the political backlash was swift, with criticism pouring in not only from Democrats, but also from some Republicans. Trump and some of his advisers did not fully anticipate the ferocious reaction — in fact, some wrongly assumed many Democrats would support the move because they had been critical of Comey in the past — and were unprepared to contain the fallout.  ...

Trump’s team did not have a full-fledged communications strategy for how to announce and then explain the decision. As Trump, who had retired to the residence to eat dinner, sat in front of a television watching cable news coverage of Comey’s firing, he noticed another flaw: Nobody was defending him.

The president was irate, according to White House officials. Trump pinned much of the blame on Spicer and Dubke’s communications operation, wondering how there could be so many press staffers yet such negative coverage on cable news — although he, Priebus and others had afforded them almost no time to prepare.

 And yes, I see there is a twitterstorm coming from Trump, which confirms that he is indeed indignant that he is copping so much criticism.
