Rick Harrison bought a name from 2 of Donald Trump‘s sons after his personal son, Adam Harrison, died from a fentanyl overdose.

A rep for the “Pawn Stars” patriarch tells TMZ … Donald Jr. and Eric Trump reached out to Rick after studying of Adam’s demise. We’re instructed the Trumps spoke to Rick on the cellphone to supply their condolences.

The Trump and Harrison households have a protracted relationship. Rick’s been a vocal supporter of the previous president for years — at one level referring to himself as a “Trump guy.”

When DT was within the White Home, he and Rick met in September 2018 … snapping a photograph along with Rick’s youngest son, Jake.

Even earlier than the cellphone name, Don. Jr commented on Rick’s tribute put up to Adam, “I’m so sorry man.”

TMZ broke the story … Adam died last week from a drug overdose.

Rick instructed us fentanyl killed his 39-year-old son and added, “The fentanyl crisis in this country must be taken more seriously. It seems it is just flowing over the borders and nothing is being done about it. We must do better.”
