The latest example of it:
The researchers found that 2.5 million Americans of Hispanic origin, or approximately 7 percent of the 35 million Americans of Hispanic origin in 2000, changed their race from “some other race” in 2000 to “white” in 2010. An additional 1.3 million people switched in the other direction. A noteworthy but unspecified share of the change came from children who weren’t old enough to fill out a form in 2000, but chose for themselves in 2010.
The data provide new evidence consistent with the theory that Hispanics may assimilate as white Americans, like the Italians or Irish, who were not universally considered to be white.
