"On July 29, 2019, the Committee received an unsolicited communication from a Federal employee setting forth credible allegations of 'evidence of possible misconduct' – specifically, potential 'inappropriate efforts to influence' the mandatory audit program," committee Chairman Richard Neal, D-Mass., wrote in his letter to Treasury Secretary Steven Mnuchin dated Aug. 8.
Anyway, back to the topic at hand; could the committee demand to see the tax returns in question, of course to determine if there was misconduct?
