The Florida Senate approved an AR-15 ban. Then they didn’t.

In a rare Saturday morning session, the state lawmakers considered a short-term ban on the assault-style rifle used to slaughter 17 people at Marjory Stoneman Douglas High School in Parkland, Florida, last month. Democratic lawmakers attempted to put the gun restriction into a bill, SB 7026, that would invest money in mental health and school safety programs.

After the upper chamber debated for nearly an hour, Senate President Joe Negron (R) ruled that the amendment temporarily banning the sale of AR-15s had passed in an unrecorded voice vote, the Tampa Bay Times reported.

A quarter-hour later, that ruling was overturned by a roll call vote of 21-17.

Every Senate member who voted against the amendment was Republican. Just two Republicans, state Sens. Anitere Flores and Rene Garcia, crossed party lines to support 15 Democrats in favor of the measure. It wasn’t enough.
