Input: Consider Input: 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
