WASHINGTON (Reuters)  - U.S. Republican Representative Tim Murphy  will resign from Congress on Oct. 21  House Speaker Paul Ryan said on Thursday  following a report alleging that  Murphy  had asked a woman with whom  he  was having an affair to get an abortion.
 Murphy  had said in a statement on Wednesday  he  would not seek re-election next year.  The lawmaker  had been a member of the Congressional Pro-Life Caucus  once receiving a 92 percent score from the conservative Family Research Council  which opposes abortion.
There was no immediate response from  Murphy ’s office for request for comment on Thursday.
The Pittsburgh Post-Gazette  citing a Jan. 25 text message  said the woman had chastised  Murphy  for asking her to get an abortion during a pregnancy scare despite  his  office posting an anti-abortion statement on Facebook.
According to the newspaper   Murphy  texted her in response: “I get what you say about my March for life messages. I’ve never written them. Staff does them. I read them and winced. I told staff don’t write any more. I will.”
 Murphy ’s extramarital affair had first been exposed in 2016 during the woman’s divorce proceedings  the Post-Gazette said.
“This afternoon I received a letter of resignation from Congressman Tim Murphy  effective October 21 ” Ryan said in a statement. “It was Dr.  Murphy ’s decision to move on to the next chapter of his life  and I support it.”
