Stephen McAllister.

Correction: An earlier version of this story incorrectly said that new U.S. Attorney Stephen McAllister reported about $1 million in annual income on financial disclosure forms. After the story published, McAllister said that figure covered a period of nearly three years, not one. Under federal rules, the disclosure form required McAllister to report income from Jan. 1, 2016, to the day he filed the form, June, 28, 2017.

Former University of Kansas School of Law Dean Stephen McAllister was sworn in as U.S. attorney for the District of Kansas on Thursday by his former boss—U.S. Supreme Court Justice Clarence Thomas. McAllister clerked for Thomas in 1991, following a clerkship with Justice Byron White. The private ceremony was held on the University of Kansas campus.

While prestigious, the new gig comes with a pay cut for McAllister, who stepped down as dean in 2005 but remained on the school's faculty.

McAllister reported more than $1 million in income from three different positions on the required financial disclosures. He said that figured covered nearly three years of income. Under federal rules, he was required to report only 18 months of income. (The rules require nominees to report income from the previous calendar year, as well any income earned up until the filing date, which was June, 28, 2017, in McAllister's case.)

According to a database of public employee salaries in Kansas, McAllister earned nearly $250,000 in 2016 from his law school job. By contrast, U.S attorneys earn less than $200,000.

McAllister will take an unpaid leave from the law school where he has taught since 1993, but will remain on the faculty, according to the disclosures. (He must obtain a waiver to participate in any matter pertaining to the University of Kansas' financial interests.) He told a local newspaper in December that he plans to return to teaching when his post as a federal prosecutor ends. The law school is McAllister's alma mater, where he obtained his law degree in 1988. McAllister has resigned his position at Thompson Ramsdell & Qualseth and his position as the state's solicitor general, according to the disclosures.

“I am honored to serve,” McAllister said in a prepared statement released by the U.S. Department of Justice. “I accept the duty to follow the law and to uphold the principles of fairness, impartiality and equal justice for all.”

In his new role, McAllister will oversee a staff of more than 100 people, including upwards of 50 attorneys.

President Donald Trump nominated McAllister to the job in September. He was confirmed in December.
