Kupec did not provide a precise time, but said it will be released both to Congress and the public.
As Congress awaits the release of Special Counsel Robert Mueller's Russian Federation report, Rep. Mike Turner of OH, a Republican member of the House Intelligence Committee, said it "gives us confidence back in our democracy".
A letter from Mr Barr last month said that Mr Mueller had found no evidence of active co-operation between the Trump campaign and the Kremlin but declined to offer a finding on whether President Trump obstructed justice - another part of the inquiry.
"The Special Counsel. did not draw a conclusion - one way or the other - as to whether the examined conduct constituted obstruction", Barr wrote.
The attorney general said Mueller did not find evidence of a criminal conspiracy between Trump and Moscow but did not reach a conclusion on whether the president obstructed justice.More news: Fenland’s Formula One ace competed well in Chinese Grand Prix

Over the past several weeks, a small group of Justice Department officials has been scouring the document to redact grand jury information and details relating to pending investigations, among other materials. In his letter, Barr wrote that the special counsel did not find a criminal conspiracy between Russian Federation and Donald Trump's associates during the campaign.
In a letter to Justice Department leaders dated March 27 but made public only today, Nunes and Representative Adam Schiff, D, cited laws that entitle the Intelligence Committee to review such information. "Everyone will soon be able to read it on their own", Barr said of the report. "Answer - Dirty Cops, Dems and Crooked Hillary!" the president added. Democrats in Congress have threatened to issue a subpoena demanding the full text. Barr noted in his summary that while Mueller's report "does not conclude that the president committed a crime, it also does not exonerate him". The attorney general told lawmakers he believed that spying on Trump's campaign did occur, and that he plans to investigate whether it was legally justified.
This means full analysis of the report will come out on Friday.
"I honestly think that will happen", Napolitano said confidently.
Barr has said he will make himself available to testify before the Senate and House Judiciary Committees next month after the report is released.
