Rachel Brand is a conservative. Was at DOJ for about 9 months as United States Associate Attorney General. Left DOJ Feb 20, 2018 to take job at Walmart. She probably learned a great deal at DOJ.
May have something to do with the restrictions placed on former government employees. See:

POST-EMPLOYMENT RESTRICTIONS
There are statutory prohibitions on a former government employee that generally prevent her from “switching sides” after leaving the government. The following are the main restrictions:
Lifetime Ban - An employee is prohibited from representing anyone else before the government on a particular matter involving specific parties in which she participated personally and substantially.
Two-Year Ban - An employee is prohibited for two years from representing another person on a particular matter involving specific parties which was pending under her responsibility during her last year of government service.
One-Year Ban - A senior employee includes Executive Level officials and all other employees whose rate of basic pay is equal to or greater than 86.5% of the rate for Level II of the Executive Schedule, which is $161,755.00 as of January 2017. Therefore, SES officials whose pay is at least $161,755.00 are covered by this additional one year restriction. As of April, 2009, Senior Level (SL), Scientific or Professional (ST), or other employees whose pay is at least $161,755.00 are senior employees, and are also covered by the additional one year restriction. Although some GS-15 employees may receive more than this amount in overall pay, they are not covered by the additional one year restriction in that their rate of basic pay is below the threshold.
Certain components of the Department of Justice are considered separate for purposes of the one-year ban. An employee who works in a designated separate component is barred only from appearing before her own component. An employee not from a separate component is barred only from parts of the Department not designated as separate. An employee paid according to the Executive Schedule does not benefit from the separation of components. She is barred from representing before the whole Department. 5 C. F.R. § 2641
