President Trump attacked special counsel Robert Mueller’s investigation as biased and unfounded Sunday, urging Republicans to get “tough” with the probe as the 2018 midterms fast approach.

Trump wrote on Twitter that Mueller’s probe looking into possible campaign collusion with Russia is evidence of a double standard compared with Hillary Clinton and that “Republicans and real Americans should start getting tough on this Scam."

“Things are really getting ridiculous. The Failing and Crooked (but not as Crooked as Hillary Clinton) @nytimes has done a long & boring story indicating that the World’s most expensive Witch Hunt has found nothing on Russia & me so now they are looking at the rest of the World!” Trump tweeted.

“At what point does this soon to be $20,000,000 Witch Hunt, composed of 13 Angry and Heavily Conflicted Democrats and two people who have worked for Obama for 8 years, STOP!” he continued.

“They have found no Collussion [sic] with Russia, No Obstruction, but they aren’t looking at the corruption… in the Hillary Clinton Campaign where she deleted 33,000 Emails, got $145,000,000 while Secretary of State, paid McCabes wife $700,000 (and got off the FBI hook along with Terry M) and so much more,” he wrote.

Trump wrote that "Now that the Witch Hunt has given up on Russia and is looking at the rest of the World, they should easily be able to take it into the Mid-Term Elections where they can put some hurt on the Republican Party. Don’t worry about Dems FISA Abuse, missing Emails or Fraudulent Dossier!"

He continued: "What ever happened to the Server, at the center of so much Corruption, that the Democratic National Committee REFUSED to hand over to the hard charging (except in the case of Democrats) FBI? They broke into homes & offices early in the morning, but were afraid to take the Server?"
