Attorney General William Barr will testify before members of Congress on March 31

WASHINGTON – Democrats on the House Judiciary Committee said Wednesday that Attorney General William Barr will be testifying before them on March 31st.

The letter says that Barr would be questioned about “the misuse of our criminal justice system for political purposes” and was confirming his “agreement to testify.”

Democrats laid out multiple issues they felt have been "dangerous for our democracy and unacceptable to the House Judiciary Committee," including pressing Barr over his handling of the Roger Stone case.

President Donald Trump tweeted on Tuesday that the sentencing recommendation for Stone, a Trump associate convicted of lying to Congress and obstructing the Russia investigation, was unfair.

Hours later, the Justice Department announced they would alter and reduce the sentencing recommendation, which prompted four career prosecutors involved in the case to withdraw. One left the Justice Department entirely.

Democrats said they would also ask Barr about the abrupt removal of Jessie Liu, the U.S. Attorney for the District of Columbia, from her post in late January.

Liu oversaw the Stone prosecution and many ongoing cases from the Mueller investigation. She was replaced by Timothy Shea, an adviser to Barr. On Tuesday, Trump withdrew Liu’s nomination to another post in the Treasury Department.

The committee also said they would ask about Trump's personal lawyer, Rudy Giuliani.

Giuliani has claimed to be digging up dirt in Ukraine about former Vice President Joe Biden and son, Hunter Biden, who has had business interests in the country.

Trump was impeached in the House on two articles stemming from allegations that he conducted a pressure campaign, with Giuliani as point man, to get Ukraine to announce investigations in Burisma. Trump was acquitted in the Senate last week.

Barr acknowledged Monday that the DOJ is evaluating information provided by Giuliani.
