(CNN) Democrats running for their party's presidential nomination in 2020 on Thursday took aim at Attorney General William Barr and demanded that special counsel Robert Mueller testify on Capitol Hill now that the full -- yet redacted -- version of his report has been publicly released.

The consistent call from the 2020 candidates makes clear that Democrats are near unified about the need for more information on Mueller's report -- specifically from the special counsel himself. The same is true for the unanimous view among 2020 Democrats that Barr's prebuttal to the release of the report -- in which the Attorney General sympathized with President Donald Trump and defended him in language the President himself has used -- undercut his impartiality.

One topic nearly all 2020 Democrats avoided on Thursday was impeachment. While the Democrats called for more information and accountability in their tweets, statements and public comments, impeaching the President was not mentioned, a signal that the political will to do so is not there. Democratic support for such a maneuver has fallen of late.

A number of candidates -- especially those in Congress -- used the release of the report to push for lawmakers to look deeper into the matter.

"It is clear that Donald Trump wanted nothing more than to shut down the Mueller investigation," Vermont Sen. Bernie Sanders, an independent running for the Democratic nomination, said in a statement. "While we have more detail from today's report than before, Congress must continue its investigation into Trump's conduct and any foreign attempts to influence our election."
