 Sen. Tom Cotton (R-Ark.)  last week helped kill the bipartisan immigration deal in Congress.  He  didn't think the bill went far enough in transforming the U.S. immigration system. Like President Trump   Cotton  thinks the United States should cut legal immigration. The senator's reasoning?
âIt can't simultaneously be true that robots will take all the jobs & that the West needs millions of new immigrants to do the grunt work â tweeted  Cotton  in late January  quoting a Wall Street Journal op-ed from a conservative commentator.
âI think itâs certainly critical that we reduce unskilled and low-skilled workers. It canât both be true ... that we need both more unskilled and low-skilled workers  but robots are going to take all the jobs â  Cotton  told Vox.
âTom Cotton is woefully misinformed â said Joe Brusuelas  chief economist at RSM. âRobots will create more jobs.â

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.”
