Research shows “there is causation between cellphone radiation and brain tumors,” according to Hunter Lundy, a personal injury attorney and lead counsel on a lawsuit against the cellphone industry.

Lundy is representing the family of the late Reverend Frank Aaron Walker. Walker died Dec. 31, 2020, at age 49, from a glioblastoma brain tumor — or what Lundy referred to as a “cellphone tumor.”

“[Walker] had tremendous cellphone exposures,” Lundy told Robert F. Kennedy, Jr. on a recent episode of “RFK Jr. The Defender Podcast.”

Kennedy also is on the legal team representing the Walker family, which names Motorola, AT&T, ZTE Corporation, Cricket Communications and the Telecommunications Industry Association as defendants.

According to the lawsuit, the defendants “downplayed, understated and/or did not state the health hazards and risks associated with cellphones” — even though they knew about them.

The lawsuit accuses the defendants of fraud, unfair trade practices, designed defects, inadequate warning and misrepresentation.
