Fighter-in-Chief

I just saw a tweet from President Trump in which he referred to Congressman Adam Schiff as "little Adam Schitt." I don't think it was a spelling error. Earlier today I saw President Trump in California telling the press that the fires were the result of bad forest management by California's leaders, who were standing near him. Today I also heard him refer to Mueller's team as "a bunch of thugs." Have we ever had a leader so willing to stand up to his enemies?
