Fox News judicial analyst Andrew Napolitano said on Monday that he believes the full report by special counsel Robert Mueller will be released after a federal judge orders an unredacted version be made public.
Kupec did not provide a precise time, but said it will be released both to Congress and the public.
The report's release to Congress and the public will come days after Barr told Congress he believed "spying" on the Trump campaign occurred during the 2016 election - a statement that buoyed Trump and his supporters, who have long argued that the Russian Federation investigation arose from false accusations and bad motives.

Smart suffered the injury midway through the third quarter, and it was initially expected to be a minor knock. Eventually, he got to his feet and, with the help of trainers, hobbled to the locker room.
Barr also wrote that Mueller presented evidence "on both sides" about whether Trump obstructed justice, but he did not draw a conclusion one way or the other. However, on the subject of whether President Donald Trump obstructed justice, Barr quoted another line from the report that said: "While this report does not conclude that the President committed a crime, it also does not exonerate him".
Although Mueller did not find a criminal conspiracy with Russian Federation, according to Barr, there is a chance the report will detail behaviour and financial entanglements that give fodder to critics who have said Trump has shown a pattern of deference to the Kremlin.
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. Barr, a Trump appointee, has pledged to be as transparent as possible.
Last month, Mueller submitted his nearly 400-page report to the Justice Department for review by the attorney general and Deputy Attorney General Rod Rosenstein.

Since those findings were announced, congressional Democrats have been sharply critical of Barr's handling of the Mueller report, accusing the attorney-general of soft-pedalling the findings to protect the president. It will have color-coded redactions.
Mueller's 400-page report most likely lays out the factual findings and legal analysis of the investigation, which resulted in numerous convictions.
After Barr released his four-page letter, Trump claimed "complete and total exoneration", condemned "an illegal takedown that failed" and accused unnamed political enemies of treasonous acts.
"I think spying did occur", Barr said.
