Question: Sen. Tom Cotton (R-Ark.) arrives for a weekly Republican Party luncheon at the U.S. Capitol on Jan. 17. (Jonathan Ernst/Reuters).
 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

Answer: Tom Cotton

 Papini  disappeared Nov. 2 while jogging near  her  home in Shasta County  about 215 miles north of San Francisco.
 Her  husband found  her  phone and earphones near their home after  she  failed to pick up their children at daycare and called police. He was initially a suspect  but the sheriff said Wednesday that the husband passed a lie detector test and offered to take another.
Authorities also said a Detroit man Papini texted and planned to meet shortly before  her disappearance  has been cleared of involvement.
 Papini  was found alongside Interstate 5 in Yolo County  about 100 miles from  her  home.  Her  nose was broken and  she  was wearing a chain restraint around  her  waist.  Her  blonde hair had been cut to shoulder length and  she  had a "brand" burned into  her  right shoulder.
Investigators declined to discuss the "brand" in detail.  Papini  has said  she  was not sexually assaulted and has described  her  abductors as two women who took  her  at gunpoint.
Sheriff's Sgt. Brian Jackson said the sketches drawn by FBI artists are being released 10 months after  her disappearance  because of  Papini 's difficulty in recalling what  her  abductors looked like.
