Wiping phones/laptops before entering the US is common practice for many organizations for over a decade now.

Not in my organization, or in any that I know of. I don't even understand why it would be in an organization's interest to do that. Why should they care if I'm harrassed for data of a political nature? They generally tell me not to even have any such data on their property.

They do, however, require that I take a burner device or wipe it completely, if I travel to China.
