House GOP Leadership's Anti-Tea Party Event Disappears From Sponsor PAC's Website

Last week, Erick Erickson reported that John Boehner, Eric Cantor, and Kevin McCarthy -- the three most powerful Republican members of the House -- would be attending a private weekend retreat at Amelia Island to discuss how to "bolster our incumbents who are under attack from the far right." The retreat is sponsored by Republican Main Street Partnership, a PAC headed by liberal Republican Steve LaTourette and funded by several Democratic Party-supporting organizations.

Since Erickson's report, Boehner has announced he will not be attending due to a "scheduling conflict."

As of today, the event has disappeared from Main Street's Events page.

Will Eric Cantor and Kevin McCarthy still attend? Is the event still on?

I have placed calls to both congressional offices. I have also contacted Main Street to ask why the event listing has been removed, and why Main Street's website contains no other mention of what would be their largest event of the year.
