For a guy who's been vindicated, he sure is mad

President Trump on Sunday continued to wage an attack against special counsel Robert Mueller, calling his investigation's report a "hit job" and claiming it was written by "The Trump Haters and Angry Democrats."

"The Trump Haters and Angry Democrats who wrote the Mueller Report were devastated by the No Collusion finding," Trump tweeted Sunday morning. "Nothing but a total 'hit job' which should never have been allowed to start in the first place!"

Trump added in a separate tweet that Democrats' investigations into him and his administration would cost them in the 2020 election.

"Despite No Collusion, No Obstruction, The Radical Left Democrats do not want to go on to Legislate for the good of the people, but only to Investigate and waste time," he said. "This is costing our Country greatly, and will cost the Dems big time in 2020!"

The tweets come as Trump continues to denounce the findings presented in Mueller's report on his investigation into Russian election interference and possible obstruction of justice by the president.

Mueller did not uncover evidence to conclude that the Trump campaign conspired with Moscow to influence the 2016 election. However, he concluded in his report that the Trump campaign knew that it would benefit from Russia's illegal efforts to interfere in the election.

The more than 400-page report also notes that Mueller was unable to “conclusively determine” that no criminal conduct occurred in regards to obstruction of justice.

Trump said Friday that some statements in Mueller's report were "total bullshit."

"Watch out for people that take so-called 'notes,' when the notes never existed until needed," Trump tweeted. "Because I never agreed to testify, it was not necessary for me to respond to statements made in the 'Report' about me, some of which are total bullshit & only given to make the other person look good (or me to look bad)."

"This was an Illegally Started Hoax that never should have happened," Trump added.

He stepped up his attacks against Mueller early Saturday in a string of tweets, calling him "highly conflicted" and once again declaring the special counsel's investigation "the greatest Witch Hunt in U.S. political history."

"Despite the fact that the Mueller Report should not have been authorized in the first place & was written as nastily as possible by 13 (18) Angry Democrats who were true Trump Haters, including highly conflicted Bob Mueller himself, the end result is No Collusion, No Obstruction!" Trump tweeted.
