(Portland, OR)  --  Mayor Ted Wheeler is walking back plans to allow public vetting of the finalists for Portland Police Chief.  Wheeler revealed only two of the four finalists yesterday, saying the other two finalists had requested confidentiality.  Wheeler's spokesperson Michael Cox says the move was prompted by feedback from some candidates who said they would only apply for the job if their candidacy was kept secret.  Wheeler had previously planned to release the names of all final candidates for public vetting.  Wheeler is expected to select the new police chief early next month.
