I e-mailed The Briefing Room months ago when non-members (not me) were unable to get on the site. They told me that they’d been overrun by bots occasionally forcing them to shut down the site. From that point on, that’s been their strategy. That’s also when I changed the site I link to here from The Briefing Room to The Right Reasons.
This is what I get when I try to access https://www.gopbriefingroom.com/
