From Lake Eola in Orlando to the White House, monuments across the country will light up blue on Sunday to kick off the start of World Autism Month.

The Lake Eola fountain will be illuminated blue from 7:30-8 p.m. Sunday — World Autism Awareness Day — as part of Autism Speaks' Light It Up Blue campaign.

The White House, meanwhile, will briefly become the "blue house" to draw attention to a "great cause," Spokesman Sean Spicer said. Trump is keeping a promise to the late wife of a friend to illuminate the building blue if he won the election. Bob Wright and his wife, Suzanne, founded Autism Speaks in 2005.
