William Barr, the Kirkland & Ellis of counsel who is set to appear Tuesday for his confirmation hearing for U.S. attorney general, reported earning nearly $1.2 million from the firm since March 2017, according to his financial disclosure.

Barr also said he anticipated receiving a $50,000 performance-based bonus from Kirkland for his work in 2018, pursuant to the firm's established compensation program. Barr has worked as of counsel at the firm since 2017, but will resign if he is confirmed by the Senate to lead the Justice Department.

Barr said he will not “participate personally and substantially” in matters for a year after his resignation where the firm or one of its clients is involved, according to an ethics agreement that accompanied his financial disclosure.

During his time at Kirkland, Barr reported providing legal services to a single client, Caterpillar Inc. The Illinois-based machinery equipment company reportedly hired Barr in 2017 after a raid by federal law enforcement officials on three of its offices.

The agreement said Barr will consult with Justice Department ethics officials in determining whether he needs to recuse himself from certain matters because they have a “direct and predictable effect on his financial interests” or those who are close to him, including his wife.

Barr,  who previously served as U.S. attorney general from 1991 to 1993, also agreed to recuse from any matter that has a “direct and predictable effect on the financial interests” on companies where he holds stocks. Barr reported a swath of stock holdings in companies, including AT&T, General Motors, Bristol-Myers Squibb, Merck and Pfizer.

Barr will divest his interests in those companies within 90 days if he is confirmed, according to his ethics agreement.

Barr also vowed to recuse himself for a year from matters involving AT&T and Time Warner, unless he gets prior authorization to participate. The two companies merged in June 2018 after the Justice Department lost its court challenge to block the acquisition. The DOJ has appealed the matter to the U.S. Court of Appeals for the D.C. Circuit, which has not yet ruled.

Barr served on Time Warner's board of directors until June 2018. Court papers show that Barr met with Justice Department officials in November 2017 as Time Warner officials urged DOJ to call off its legal challenge to the merger.

He reported earning over $300,000 in his director role, but picked up over $1.3 million from the company after exercising his stock options.
