President Donald Trump praised Attorney General Bill Barr on Tuesday for appointing a U.S. Attorney to investigate the origin of the FBI investigation which led to spying on his presidential campaign.

“I am so proud of our attorney general that he is looking into it,” Trump said, “I think it’s great.”

The president commented on the news as he left the White House for a trip to Louisiana.

The New York Times reported Monday night that Barr had appointed U.S. Attorney for the District of Connecticut John Durham to investigate the origins of the investigation into the Trump campaign in 2016.

Trump said that he was not aware of Barr’s decision beforehand.

“I didn’t know it, but I think it’s a great thing that he did it,” he said. “I saw it last night. They want to look at how that whole hoax got started.”

Trump again called the investigation the “greatest hoax ever perpetrated” on the American people and the presidency.

“Even Mueller, not a friend of mine, even Bob Mueller, came out – no collusion,” he said.
