U.S. lawmakers tried adding crypto conflict-of-interest rules to the CLARITY Act, targeting officials like Trump.  
The White House blocked it on June 11, stopping bipartisan compromise.  
The clause aimed to restrict leaders from profiting off crypto while in office.  
A "ban Trump from crypto" amendment also failed 21-30.  
Talks continue for alternative wording before July’s recess.  
But Democratic support is shaky, risking Senate approval.  
Trump’s crypto ventures reportedly earned him $3.
