Senators Ron Johnson (WI) and Chuck Grassley (IA) fired off a Wednesday letter to the Justice Department after discovering that the DOJ "could not locate 59 of the 96 phones used by Special Counsel Robert Mueller's team," according to a press release on Grassley's website.

"Further, the Justice Department failed to review over twenty phones for federal record preservation," the statement continues.

The Wednesday letter follows up on a September 2020 request regarding allegations that cellular phones assigned to "multiple people on then-Special Counsel Robert Mueller's investigative team were 'wiped' for various reasons during [the Russia investigation]."
