Acting Attorney General Todd Blanche is testifying before the Senate Wednesday and is likely to face questions about some controversies.

July 15 (UPI) -- Acting Attorney General Todd Blanche is testifying before the Senate Judiciary Committee Wednesday and is likely to face questions about a host of recent controversies.

Blanche, President Donald Trump's former defense attorney, is seeking confirmation as attorney general, and these questions could complicate that road.

Blanche needs every Republican vote in the Senate to be confirmed, and in recent months, several Republicans have voiced concerns with his actions in office.

Blanche has served as acting attorney general since Trump fired Attorney General Pam Bondi in April, and he was formally nominated in June.

Making his run to confirmation more contentious is the death of Sen. Lindsay Graham, R-S.C., who was expected to champion Blanche to his Senate colleagues. Graham was also a member of the Judiciary Committee.

In May, Trump settled with the IRS for $10 billion after suing the department for leaking his tax returns. Then Blanche created and signed a document giving the president and his family immunity from IRS investigations. He also helped orchestrate the "Anti-Weaponization Fund," which Trump planned to use to give money to people he believed were being targeted with prosecution he disagreed with. The fund is now defunct, Blanche announced in June.

On Monday, a federal judge threw out the settlement with the IRS, saying Trump filed the suit for an "improper purpose." She also referred Trump's attorney in the case and Blanche to their state bars for possible disciplinary measures.
