Man Who Threatened Sen. Ernst Sentenced to Federal Prison
WATERLOO, Iowa — A Waterloo man is headed to prison for threatening Iowa senator Joni Ernst.
Thirty-four-year-old Joseph Dierks was sentenced Wednesday to six years in federal prison.
Dierks directed a series of tweets at the senator last year including one that suggested he would shoot her.
He was convicted in November of three counts of sending threatening communications.
