Some 30 cars, many on Gores Drive in Mastic on Long Island, were spray-painted by vandals on Tuesday night.
The graffiti includes racist slurs and sexually graphic references. One Mastic resident says "kill Obama" was written on a vehicle.
A Secret Service spokesman in Washington says the agency's Melville office is cooperating with a Suffolk County police investigation.
Residents say the neighborhood is usually "harmonious and diverse."
Another incident occured in Mariner's Harbor on Staten Island. Racist graffiti was sprayed outside the homes of African-Americans in the area.
"This is a community that has more than one race in it," Judy James said. "It's a real nice community, and we should not be having this here."
Neighbors counted over two dozen swastikas over two blocks.
