I called VFW, too. Their communications director said that the VFW routinely provides its space to almost any organizations. The supporters standing behind B were primarily Marine Corps League, and there was no way—other than by calling the CT branch sponsor of the event, and even that branch might be unable to identify any of the other gentlemen—to determine whether or not they were also VFW members. He, he said, had noticed no VFW caps.
The Connecticut VFW Cdr. has released a statement by this time (it wasn’t ready at the time of my call) that should be accessable on the CT VFW site. The National Office will take no position, make no statement. They’re audited by Congress, so they’re careful about IRS regs.
