President Donald Trump on Monday, June 22, accused former President Barack Obama of treason for spying on his campaign in the course of the Russia investigation in 2016.

“Treason. Treason. It’s treason,” Trump said in an interview with CBN News. “Look, when I came out a long time ago, I said they’ve been spying on my campaign. I said they’ve been taping, and that was in quotes, meaning a modern day version of taping, it’s all the same thing. But a modern day version. But they’ve been spying on my campaign.”

“Turns out I was right,” the president continued. “Let’s see what happens to them now.”

The president went on to point to U.S. Attorney John Durham’s ongoing investigation into the origins of the Russia probe.

“I want to stay out of it because otherwise it’s going to look political,” President Trump said. “Let’s see what they come up with.”

Last month, Obama was put in the spotlight after Department of Justice’s documents showed that the former president knew about the details related to then-incoming National Security Adviser Michael Flynn who was targeted by the FBI during the presidential transition period.

However, Attorney General William Barr said he did not expect that Durham’s work will lead to the criminal investigation of Obama or former Vice President Joe Biden.

“Our concern over potential criminality is focused on others,” Barr said.

During a Fox News interview with Maria Bartiromo on Sunday, Barr hinted that there soon may be “developments” in Durham’s investigation.

“In terms of the future of Durham’s investigation, you know he’s pressing ahead as hard as he can, and I expect that we will have some developments hopefully before the end of the summer,” he said.

Separately, Senate Judiciary Committee Chairman Lindsey Graham (R-S.C.) has revealed that he wants to release the findings of his investigation into the federal Russia probe before the November election.

Graham’s committee earlier this month approved subpoenas for documents and testimony from top Obama administration officials as part of its investigation into the origins of the Russia probe. The subpoenas apply to former FBI Director James Comey, former National Security Adviser Susan Rice and former Director of National Intelligence James Clapper and others.
