The prosecution was handled through a grand jury in Portland and is being announced by the Obama US Attorney in Oregon under whose auspices it operated.
Billy Williams is a career prosecutor appointed to fill the US Attorney slot by Loretta Lynch in December 2015.
Attorney General Jeff Sessions did not ask for or receive Mr. Williams resignation when he took over at the Justice Department.
I find it interesting that Williams is acting in what may be his final days in his position.
Word from Oregon is that the Trump Administration could appoint its US Attorney for Oregon by the end of this month.
Obama fired all the US Attorneys pretty quickly.
What did Trump let them stay on?
