WATCH: Sen. Mazie Hirono accuses AG Barr of lying to Congress. Chairman Lindsey Graham is having none of it.

Sen. Mazie Hirono (D-Hawaii) pulled no punches against U.S. Attorney General William Barr during her allotted time at Wednesday's Senate Judiciary Committee hearing where the nation's top law enforcement officer was testifying.

During her minutes-long diatribe, she personally attacked Barr and accused him of breaking the law by lying to Congress, but committee Chairman Lindsey Graham (R-S.C.) was having none of it.

"Listen," Graham said, interrupting the end of Hirono's repeated attacks on Barr's character, "you've slandered this man."

"I do not think that I am slandering anyone," Hirono replied.

"All I can say is I gave you seven minutes and you've slandered this man from top to bottom," Graham told Hirono. "So, if you want more of this you're not going to get it; if you want to ask him questions you can."

"You certainly have your opinion and I have mine," Hirono replied with a tight-lipped expression.

What did Hirono say to Barr?

"The American people know that you are no different from Rudy Giuliani or Kellyanne Conway or any of the other people who sacrificed their once decent reputation for the grifter and liar who sits in the Oval Office," Hirono began her remarks against the attorney general.

She went on to accuse Barr of lying about special counsel Robert Mueller's reported concerns about the attorney general's four-page summary of the Russia investigation's findings.

"You used every advantage of your office to create the impression that the president was cleared of misconduct," Hirono said to Barr about the summary. She also accused him of selectively quoting from the Mueller report and taking key sections "out of context."

"You put the power and authority of the office of the attorney general and the Department of Justice behind a public relations effort to help Donald Trump protect himself," Hirono added.

She then accused Barr of "deep involvement in trying to cover up for Donald Trump" and said that he should leave his job as a result.

"Being attorney general of the United States is a sacred trust," Hirono concluded. "You have betrayed that trust, America deserves better. You should resign."

The full seven minutes of Hirono's allotted time can be seen below.
