Barr added, "I think spying on a political campaign is a big deal".
This is to say that what Barr is talking about appears to be separate from the complaints lodged by one Carter Page, the former Trump campaign adviser who was the target of such warrants.
"I think spying did occur", he said.
'The generation I grew up in, which was the Vietnam War period, people were all concerned about spying on anti-war people and so forth by the government.
Barr said that after releasing a public version of Mueller's report - with some sections redacted - he will talk to leaders of the Senate and House Judiciary panels about providing them more information.
"I have not seen the Mueller report".
Barr was discussing his plans to investigate the FBI's decision to open a counterintelligence investigation against Trump campaign associates.
At least some of the information that underpinned the request came from a former British intelligence officer, Christopher Steele, who also was the author of the infamous Russian Federation dossier.
She said again, "Let us see the report".
'What I'm most interested in is getting started. on going back to the origins of exactly where this all started, ' the president continued, repeating his call for an investigation of the origins of the Russian Federation probe.
But that was before Barr released his four-page analysis of Mueller's report, which said the president was not exonerated by the special counsel. Trisha Anderson, the former No. 2 lawyer at the Federal Bureau of Investigation, testified to congressional investigators in August 2018 that she signed off on the FISA warrant application on former Trump campaign adviser Cater Page without reading it, due to the involvement of other high-ranking Federal Bureau of Investigation officials. The president did not name them but has previously blamed Justice Department officials and former FBI Director James Comey. He said that the letter may have been read to them, but they did not get a hard copy of it. And I'm not suggesting that it wasn't adequately predicated.
We also know that key FBI agents involved in the investigation were fiercely opposed to Trump.
And in his role as attorney general, Barr has shown that he is adept at manipulating the media to spread the kind of storyline that suits his purposes, even when it isn't supported by the underlying facts.
Spying on the Trump campaign certainly occurred.
Trump also stated that "I don't care" about the report from special counsel Robert Mueller that Barr says he will release in the coming days in redacted form.
It was Hillary Clinton's campaign, as well as the Democratic National Committee (DNC), which had hired Fusion GPS-through their law firm Perkins Coie-to produce the dossier.
