But Democrats largely trained their fire throughout Monday on Barr, who was confirmed to his job in a 54-45 vote largely along party lines.

Barr deliberately deceived the public about the Mueller report, and he’s deceiving the public again by ignoring the IG’s finding that opening the Trump/Russia investigation was justified. — Senator Mazie Hirono (@maziehirono) December 9, 2019

Sen.(D-Md.) added that "Barr should stop covering up for Trump and stick with facts."
