If you thought summer traffic was already bad in the Hamptons, just wait until Friday — when President Trump comes to the East End for political love fests.

The president is set to appear at a posh, cozy morning huddle hosted by Related Companies’ developer Stephen Ross in Southampton, sources said. He then heads to another event for up to 500 of his nearest and dearest at the Bridgehampton estate of well-known local developer Joe Farrell.

Route 27 will be closed for at least a half hour before and after Trump’s arrivals and departures, sources said.
