A whistleblower revealed the horrific plan at the Social Security Administration.

The Trump administration had plans to falsely declare 2.7 million people dead as part of the president’s cruel mass deportation efforts, The Washington Post reported Friday.

A 49-page whistleblower disclosure reviewed by the Post detailed how the White House plotted to add the names and Social Security numbers of millions of living, breathing people to the Social Security Administration’s Death Master File, or DMF, which is used to track when a person has died and should stop receiving government benefits.

Whistleblower Jeremiah Schofield, who worked at the Social Security Administration for 25 years before leaving in October, told the Post that he’d refused to implement the plan. Schofield said that when he pulled a sample from the 2.7 million names, he found that all of the people marked for death were still alive. Agency lawyers had warned that falsely marking someone as dead could violate federal law, and Schofield realized that the plan’s purpose was to terrorize immigrants.
