President Donald J. Trump announced his decision to demand an official investigation of former President Barack Obama’s administration on Sunday for infiltrating or surveilling his presidential campaign for political reasons.

“I hereby demand, and will do so officially tomorrow, that the Department of Justice look into whether or not the FBI/DOJ infiltrated or surveilled the Trump Campaign for Political Purposes – and if any such demands or requests were made by people within the Obama Administration!” Trump wrote on Twitter on Sunday afternoon.

Trump frequently blames investigations of his campaign on Obama, suggesting that politically motivated investigators were unfairly targeting his campaign.

He spent most of Sunday morning sharing his thoughts on Twitter about the ongoing Russia investigation, suggesting that the ongoing “witch hunt” was out of control. “Things are really getting ridiculous,” Trump wrote, noting that so far there was no collusion found by special investigators.

He criticized Special Counsel Robert Mueller’s team as “13 Angry and heavily conflicted Democrats” who were part of the Obama administration.

“STOP!” he wrote. “They have found no collusion with Russia, No obstruction.”

Trump again redirected the continuing investigation towards failed presidential candidate Hillary Clinton, Democrats, Tony Podesta, the DNC, and politically biased FBI officials.

“Republicans and real Americans should start getting tough on this Scam,” he wrote.
