— -- A salacious, accusatory email and a covertly-obtained audio recording on a cell phone resulted in the downfall of two Michigan State Reps. Todd Courser and Cindy Gamrat, elected into the Michigan House of Representatives in November 2014, ultimately lost their seats and subsequent re-election campaigns due to their romantic extramarital affair and attempted cover-up.
In the midst of their affair, Courser said he began receiving 'blackmail texts,' threatening to come forward with information about his relationship with Gamrat unless he resigned as Representative.
He then asked his house aide Ben Graham to send out an anonymous email accusing him of drug-use and 'male on male sex.'
Instead, Graham recorded the conversation and gave it to Detroit News reporter Chad Livengood.
Both Gamrat and Courser, ex-staffers Keith Allard and Ben Graham and reporter Chad Livengood sat down for an interview with ABC News "20/20.”
Below is a timeline of the key events from the affair.
Nov. 4, 2014
Gamrat, a homemaker from Plainwell, Michigan, gets 63 percent of the vote in the 80th district, and Courser, a lawyer from Lapeer County, Michigan, gets 55 percent of the vote in the 82nd district to win their respective elections for Michigan State Representative.
At the time they entered office, both Courser and Gamrat were married. He has four children and she has three.
