Rep. Tim Murphy (R-Pa) plans to resign on October 21, 2017. This announcement is likely based almost entirely on the scandal involving Murphy having an affair with a forensic psychologist named Shannon Edwards, then asking the mistress to have an abortion in the midst of a frightening pregnancy scare. Murphy has presented himself to the public as pro-life. Allegedly asking a mistress to have an abortion bears a slight conflict of interest to his beliefs and work as a Pennsylvania state representative.
Murphy is under fire because he recently voted in support of a bill that banned abortions at 20 weeks, but his scandal involved leaked text messages reportedly showing him ask Edwards to have an abortion. Edwards later learned that she was not pregnant.
Tim Murphy expressed plans to retire at the end of his term and utilize personal time to work through familial issues while the scandal settles. His resignation plans have likely replaced the retirement plans which would have seen him finish his term.
