Fer shits-n-giggles, I searched for 'us criminal code 11.3' in startpage, and the second response was a link to Title 18 in the U.S. Code. Section 1 is 'Crime', and its chapter 11 is 'BRIBERY, GRAFT, AND CONFLICTS OF INTEREST'. The 3rd section in that chapter is this: '§ 203.Compensation to Members of Congress, officers, and others in matters affecting the Government'

It's a gigantic stretch I know, but still, the section itself seems relevant to the current situation, CF, etc, so I shared it anyway.
