White House senior adviser Stephen Miller's uncle appeared on CNN Friday to slam his nephew's immigration policies.

Dr. David Glosser, a retired neuropsychologist, said that his nephew is an "immigration hypocrite."

"Our family wouldn't have survived or existed had it not been for the opportunity to immigrate to the United States as refugees back in the early 1900s," he explained.

"On the other hand, those that were unable to come after the 1924 Immigration Exclusion Act, all 74 of those were murdered in World War II. So Stephen would have never existed."

Glosser made similar arguments in an op-ed for Politico that he wrote in August of this year. His appearance on CNN escalates the family feud and is also notable given the animosity between the cable news network and Trump White House.

Miller has been credited as being the architect behind the Trump administration's hard-line immigration policy.

Glosser said that the current situation with immigrants at the southern border reminds him of his own family's struggles to get to the U.S.

"We're getting no moral leadership whatsoever from the president, who is happy to condemn these people who are like our family ... who are desperately fleeing terrible oppression and danger."
