Since Trump cult members INSIST that Trump can unilaterally stop the disclosure of his tax returns, I had to look up what the LAW (not acolytes) state about such returns' disclosure
26 U.S. Code § 6103 - Confidentiality and disclosure of returns and return information
(f)Disclosure to Committees of Congress
Secretary shall furnish such committee with any
return or
return information specified in such request, except that any return or
return information which can be associated with, or otherwise identify, directly or indirectly, a particular taxpayer shall be furnished to such committee only when sitting in closed executive session unless such taxpayer otherwise consents in writing to such disclosure
