I am both surprised and not surprised by this decision. For Gaetz, this is a huge win although it is by no means the end of this report. There is a solid chance that Democrats will use a maneuver called a privileged resolution to force a full House vote on the matter. Gaetz still has tons of enemies in the House on the Republican side who would happily vote with the Dems to force this report out into the open.
Also this doesn't stop the Senate from going after this report as well. We have already heard that the DOJ is going to turn over their investigation and evidence against Gaetz.
