Cheddar's Chloe Aiello joined "Closing Bell" to break down the progress of the SAFE Banking Act in Congress as cannabis businesses operators struggle to find financial institutions that will service them. Banks face steep federal penalties, including the risk of losing a bank charter, if found to be servicing marijuana businesses even if their state has legalized operations. Aiello reported that while there was some bipartisan support for the measure in the Senate, the bill faces some opposition from conservatives with "longstanding concerns" about cannabis and progressives who prefer a more comprehensive approach to reform.
