Trump Tweets: 'NO COLLUSION!'

Business Insider reports that President Donald Trump tweeted an all-caps rebuke, Saturday, of special counsel Robert Mueller's investigation. Mueller has been investigating Russian interference in the 2016 US election and possible Trump campaign collusion.
Trump wrote of the investigation, "AFTER TWO YEARS AND MILLIONS OF PAGES OF DOCUMENTS (and a cost of over $30,000,000), NO COLLUSION." The investigation is estimated to cost nearly $17 million.
