Barr described this approach as a standard practice in which officials at the Department of Justice (DOJ) often rely on the characterization of the evidence uncovered in an investigation.

"We accepted the statements in the report as the actual record. We did not go underneath it to see whether or not they were accurate. We accepted it as accurate," Barr said Wednesday while testifying before the Senate Judiciary Committee. ADVERTISEMENT

Barr, however, sought to defend his handling of the report.

"Prosecution memos go up to the supervisor. In this case it was the attorney general and deputy attorney general who decide on the final decision, and that is based on the memo presented to the U.S. attorney’s office," Barr said.

"We presented the evidence presented in the report. This is not a mysterious process. And in the Department of Justice we have cross memos and declination memos every day coming up, and we don’t go and look at the underlying evidence. We take the characterization of the evidence as true," he added.

His statements come at a time when Democratic scrutiny of the attorney general's handling of the Mueller report is reaching a fever pitch. Democrats, who have accused Barr of acting as the president's defense attorney, increasingly are calling on Barr to resign.

Barr has faced sharp backlash from Democrats for his handling of Mueller's more than 400-page report on his investigation into Russian election interference and possible obstruction of justice by Trump. The attorney general in March delivered a four-page summary of Mueller's investigation to Congress — a summary that the special counsel pushed back on.

A Justice Department spokeswoman said Tuesday that Mueller expressed “frustration” to Barr over the lack of context in his memo describing the special counsel's investigation’s findings.

Barr’s letter was sent nearly a month before he released a redacted version of Mueller’s 448-page report. Trump has seized on the report's findings as exonerating him of any alleged wrongdoing.
