Over the weekend, Brown released copies of money orders totaling more than $600 that he alleges he received from Howard Brooks, a Gray campaign aide.
The Washington Post reports Brown offered up the money orders to the paper after it questioned him about his campaign records, which show, according to the Post, that several relatives or friends of Howard Brooks may have contributed money to Brown's campaign.
Mayor Gray says he did promise Brown a job interview. Brown was ultimately hired by the Department of Health Care Finance after Gray took office, but was fired after about a month. Gray denies any knowledge of cash payments.
For weeks, the D.C. Council has tried to get Brown to testify on the record, issuing him a subpoena to appear at several hearing investigating the accusations. Today, the council members get their wish as Brown has said he will show up for today's hearing.
