The difficulties for marijuana businesses to work with banks has been well-documented over the past several years, and it finally seemed like Congress would open the doors to make things work. But apparently they decided to continue making life difficult for cannabis companies.

The House Appropriations Committee rejected a measure that would've protected banks that open accounts with marijuana businesses. The bill would've prevented the Treasury Department from penalizing banks or financial institutions from working with cannabis companies if they were operating legally within their state.

Supporters of the bill framed it as a public safety and financial transparency issue. Many cannabis companies cannot work with banks, and therefore operate as cash-only businesses. This often makes them the target of robberies. 

A similar measure was actually based by the House in 2014, but the amendment didn't make it into the final funding bill for the Treasury and therefore did not become law. Since then, Republicans have been resistant to nearly all marijuana-related proposals. 

The unfortunate thing is many believed this banking proposal would pass. Several members from both parties indicated their support, but some supporters did not attend the vote and others said they weren't 100 percent sure about the actual proposal, which led to its defeat.

Can you name another legal business that's denied access to banks in America?
